Durable, Reliable, Basic
I wanted a basic, no apps, no jazz, water resistant watch to track the time I spent walking my senior dog and the breaks he took. I originally purchased one for me back in 2021 and loved it, it is a tough little guy I must say. The step counting was an added benefit, I began to pay attention to it bc of the watch. This one that I'm leaving a review for, I purchased for my mom as she loved my basic watch. We went to the beach for 4th of July weekend and her and I forgot we had our watches, mind you mine 2 yrs old and hers is newer, we went in the water, both watches survived, we were both super impressed. Battery life is good, mine goes dead after 3 days of zero charge, even when the battery is at one bar it still lasts. I love the easy USB port charging and charges super fast, I charge anywhere there is a USB port, no need to carry chargers. I've read that set up is difficult, but for me it was intuitive and the instructions were pretty easy to follow. It has one main button and you touch it to navigate the menus, when you reach the settings icon you just hold it down for a couple of seconds till things begin to blink and you can change them. Now, to leave your selection just hold the button and it saves them, simple! But I can see how for someone like my mom who is in her 60's this was a bit frustrating, so I just did it for her. I use mine every day, the plastic is durable, comfortable, doesn't rip any arm hairs and easy to wash. I'm very petite, with little wrists, and it doesn't feel clunky at all. After 2+ yrs the plastic gets a little dull (still flexy) screen has some scratches, but hey I live a very active lifestyle and use it every day! If you are one of those "they don't make them like they used to" and value durability, this is it for a basic, durable watch. I love mine!

Accept it with a grain of salt
The frustrating part is the programming. It is very sensitive when it comes to moving from one program to another and inserting your data. My first several attempts were a nightmare of frustration and I had to hold myself in check to prevent myself from tossing it at a wall or stomping on it. That was with the first watch. But that pattern repeated with the second watch which arrived a week later. For accuracy, here is the comparison. I am utilizing this watch primarily as a pedometer. I put both watches, same brand, both fully charged, onto the same wrist and went onto a stepper. The results were the purple said 3948 steps while the green put the steps at 3388. The difference is 560 steps. That is a lot. And I don't know which - if either - is accurate. (Steppers are notoriously inaccurate, even if they appear to work - mine doesn't - hence the wrist pedometer.) Whichever wrist you wear your watch on, that arm needs to be in swing motion for the pedometer to function. The color of the band is true to what's on-screen. I ordered the green then followed that up with the purple. In dim light the band looks more brown than purple, but in light it is definitely purple. Contrary to the initial programming, after that it's functional and easy to flip through your stats. If you're going to charge into a socket, you need the adapter but otherwise the watch charge mechanism is on the unit. There is no cord involved. That requires removing the band on that side. But the band is easy to push on and pull off. Not fancy but a sleek design that also has a variety of band colors available. Lightweight. Not chunky. No app or cell connection. Not SMART. It's an independent unit so you access your results immediately. UPDATE: Still have the green one but the purple strap one needed the battery charged as I was using that more often. The battery was half empty. I used the same adapter for charging as last time but went through several outlets and it did not charge. In fact, it dropped further on battery usage. This is a return item. We'll see what the lifespan of the green strap watch pedometer is.

Simple, No Frills but functional
Simple, but it does the job well. It took a little bit to get used to the fitness tracker since there is no charger- rather the watch itself plugs directly into the USB, the directions that come with it are very clear though. To get it set up only takes about 5 minutes, and it's very comfortable to wear. Additionally and I like the size for my small wrist. I need to adjust the step counter stride length because I am tall- but that should be pretty easy to do. I have only been wearing it a day, so I am not sure what the sleep functioning is like yet. Overall I really like it. There is something nice about the simplicity of the watch face, and the straightforward step-counting function that makes it my current go to watch.

No Apps, No Sync, Just Works Perfectly🌟
🌟it’s incredibly easy to use, and its simplicity is one of its biggest strengths. Everything you need is right on your wrist, no apps or syncing required. The battery life is excellent and lasts much longer than I expected, which makes it ideal for everyday use. Overall, it has exceeded my expectations!🌟

Okay tracker, mediocre battery, not easy to clean
The actual tracker is okay- it doesn't record as many steps as a Fitbit (I literally wore both on the same wrist for an entire day, this one tracked about 1500 steps less than the Fitbit over the course of the day). I like that it doesn't use bluetooth- we have concerns about Bluetooth usage, but also, it's way less stressful to track steps without an app. I can't see previous days steps, which could be a turnoff for some folks, but I kind of love it because it takes the pressure off. Each day is its own day and all I have to do is my best. Other things to note- the battery life is terrible compared to the Fitbit, but I've learned is probably comparable to a lot of apple watches. Best I can get is about 2 days with this device, but since I opt not to wear it at night, it's not a big deal for me. It seems there is a sleep timer, but it doesn't track your sleep like other brands, which again, is a plus for me, but could be a negative for someone else. What I like the least about this watch is how dirty it's gotten and will not come clean. Granted, I chose the white band, and my Fitbits white silicone band wasn't much better, but I could at least purchase a new band with that company. I haven't yet found an option to purchase a new band without purchasing a whole new tracker, which isn't very expensive... but seems wasteful. Also, I have scuffed the face a bit, which I also did with my Fitbit so that has more to do with my own clumsiness than the design itself. It was pretty easy to set up, and the simple design face was not a problem for me. There are not extra options for face styles, which might matter to some buyers but I don't mind. All in all, I would purchase again (and I might for my child) but not a light colored band. I like the app free, Bluetooth free option for tracking steps, and the battery life is a little annoying but not terrible. I would quickly raise this to 4 stars if I were able to purchase a new band without buying a whole new watch, but I think it would need a few other things improved to reach 5 stars (primarily the battery life and improved step count).

Simple and functional
This watch does exactly what it’s supposed to do. It’s easy to use, doesn’t require a phone connection, and tracks steps and calories well. I like it because it’s comfortable and practical for everyday use. Great option if you’re looking for something basic and affordable

Does not keep track consistently
Not sure if mine was faulty but I noticed that it did not track my steps consistently. I wanted a pedometer/watch that didn’t require an app to keep track, and I was really excited to find this! I set the step distance to 24” (2 feet) at first, then 18” (1.5 feet), and then 12” (1 foot) to test the unit. I kept it at 12” for a month and purposely went on a daily walk doing the same exact route/distance to test it. The results were quite different. I tested it by swinging my arm (where I wore it) and counting the steps I took, and it would only count some of my steps some of the time. I tested it along with my phone’s pedometer and again, different results. I tried strapping it to my shoe and wearing it for a whole day and the results were really “off”. I noticed that it would do a better job of counting steps when the unit was pressed tight against my wrist, but I prefer to not feel like my wrist is being strangled in order to get an accurate read. I charged it every few days when the battery icon showed it was more than halfway down from full, and noticed that it would show a bunch of super small print on the screen quite often, which would only go away after I pulled it out of the wrist strap and plugged it into the power block - even if it didn’t need to be charged. Odd! I was basically wearing it just as a watch after discovering the inaccuracy of the pedometer feature (which is what I bought it for, grrr) but the screen would default to it’s “tiny print” mode more and more often. It has become a nuisance having to pop it out and “reset” it basically every day in the past week, that I no longer wear it at all. Disappointing.

Works for specific use cases. No EMF's, smartphone, privacy issues.
I've been trying this device for a few days. It works for some very specific use cases. It does not produce substantial EMF's as it has no BlueTooth or wifi. It requires no smartphone or app and does not present privacy concerns with an app provider monitoring everything you do. It provides clock, steps, distance, calories, and a manual sleep timer. Note that any device that's measuring calories without an accurate heart rate count is only giving a gross approximation for an "average" person of the gender and weight you enter and "average" walking. Even with heart rate, it's an approximation. This device does not measure heart rate. High accuracy calorie counting requires treadmill / oxygen use testing. As such, I don't care about the calorie counter. I was mainly interested in step counting. If you input your accurate stride length, your distance numbers should be good IF the step count is accurate. Note that this is NOT a GPS device. The problem is that the step count is frequently NOT accurate. According to my testing with a manual tally counter (clicker), the device records steps while walking for exercise pretty well. It was accurate to within just a few steps out of 100. But, the problem is that it's not accurate when not exercising. WHAT? you say. It records phantom steps when it shouldn't, and this falsely inflates the step count. For example, if get out of a chair and go to the bathroom, do my business, wipe my nose, wash my hands, dry my hands, and return to my chair, the unit will record about twice as many "steps" as it should. All that hand movement messes it up. Also, it recorded several hundred bogus "steps" while driving in my car for about 7 miles on common paved roads. The cumulative effect is that the step count, distance count, and calorie count are way too high at the end of the day, assuming I go to the bathroom a few times and drive a few times. So, here's the only way I can see using this device. Say you are actually going to walk for exercise. You note the step count before starting. Go do your walking. Note the step count at the end. Then subtract the two numbers to get the net, which should be pretty accurate. Otherwise, ignore the step count during the day. The unit has no reset button, but the count resets every night. It does not keep any long term records. I'm probably going to return this and try a belt / lanyard / pocket pedometer from RealAlt. This unit also has a feature where it turns on the display light when you rotate your wrist. That's OK if you want to read the unit. But, my wife said it turned on during the night while I wasn't trying to access it. Apparently, this also happens with the sleep timer on. So, this might bother you or your mate while you're sleeping. If the RealAlt pedometer is not as subject to false readings and / or if I can reset it on demand, I'll probably use that instead. Based on my reading, many pedometers and fitness trackers, even expensive ones, are subject to these false measurements. If the other one also accumulates false steps, I'll have to reset it each time I exercise, and the daily and 30 day accumulated numbers will be wrong. Note that comparing one pedometer to another isn't very useful. The only way to know if one is accurate is to compare it to a manual tally counter where you click it on every step. Or, you can click it on every other step and multiply by two. This tells you if it's properly counting steps when it should. Then, you can check the pedometer to see if it gives false readings when it should not be counting steps. If you think you can live with these limitations for this unit, it might be useful to you. Otherwise, you may wish to look elsewhere. Note that it is VERY hard to find fitness trackers that don't produce EMF's. The Bluetooth and / or WiFi can be turned off on some of them, but not all. Almost by definition, the smart bands and smart watches are going to be pretty dependent on their wireless functions and connection to a smartphone or tablet. Ron
