Your next best friend
I used to have an old-fashioned jar opener similar to this one. It was probably from the 1950s and something I had found at a garage sale years ago. I absolutely loved it, but over time it finally wore out. I have fibromyalgia in my hands, and sometimes it’s very hard for me to open jars or bottles. Some days it’s even difficult just to hold onto things, so when my old opener quit working, I honestly panicked wondering what I was going to do. I’ve tried those rubber grip cloth things you put over lids, but they just never worked well for me. Then I saw this and thought I’d give it a try. Oh my goodness — this thing is the next best thing since buttered bread! It works so well. It opens all different kinds and sizes of jars and bottles with very little effort. It has made such a huge difference for my hands. I am so thankful I found it. The quality is also excellent. It feels sturdy, well made, and not flimsy or cheap at all. On top of that, the price was fantastic. If you have arthritis, fibromyalgia like I do, weak hands, or just struggle opening things, you truly need one of these. Trust me, it will become your best friend in the kitchen. Thank you so much for making such a wonderful product!

A Must-Have Jar Opener for Arthritis—Simple, Affordable, and Effective
I have arthritis in my hands, and opening jars has become increasingly difficult. I decided to try this inexpensive jar opener, and it has been a game changer. I’ve been using it on jars of all sizes—from very small lids to large, stubborn ones—and it works incredibly well. The design allows you to get a solid grip on the lid, making it much easier to twist and open without straining your hands. What used to be frustrating is now effortless. Pros: inexpensive, cost-effective, works on multiple jar sizes Cons: none so far Tips: Make sure you match the lid size to the correct opening on the device for the best grip and easiest results. Overall: High value and highly recommended—especially for anyone with arthritis or reduced hand strength.

These work perfectly. Finally someone figured out how to make one of these at work
I cannot believe how well this works. I thought it might be a waste of money. I was wrong. Jars are very tight, with a good grip it comes right off. No more hurting your hands or getting something to bang on the lid to get it open. Seems very durable. Nice and thick for the good grip. I've used each of the bottle sizes and they all work perfect.

Good for poor hand strength
This has been GREAT for my grandma with RA. It’s portable, durable & works fairly well for poor hand strength! When she is having a flare up, she does struggle to grip & turn the tool, but still is able to use it.

Good Jar Opener For Sprained Thumb
Good jar cap opener. I like the size options and watched customer videos to see it working. It's good help for my sprained thumb guessing hurt from straining at jar lids. Flimsy round pads are not effective and heating jar lids with hot water, banging lids with spoon handles. I tried to make my own jar opener with metal parts, but not effective enough. I'm wearing a thumb support recently ordered from Amazon, and hurt thumb again trying to open a stubborn jar cap to order the Otstar Opener. As soon as it was delivered, I tested it to work well on screwed on caps, but not push down safety caps/lids like on supplement jar in attached photos. To show jar lid in second photo, I propped up new opener with an empty jar. (Corrected misspelled rund to round).

Opens OK if your lid fits
This opener works well as long as the lid of the bottle fits snugly within one of the four varied-size openings in the item. (See the photo illustrating the relative sizes of the holes using a 12-inch ruler.) When I purchased this, I was thinking that the opener was hinged and you just used it like a pair of pliers to get a screw-top lid open, but this has four preset hole sizes, albeit they are usually the size of lids you have to deal with. There is a little flexibility in the gripper, but not much so you pretty well have to be content with hoping that the lid you are trying to open fits. For this potential problem --- and I have encountered a couple of lids that did not fit --- I gave only a three-star rating.

Does the job!
Used it only once but it’s a winner! Super easy to use and easily opened a salad dressing bottle that would have had to go back into the pantry until someone came over that had more muscle and no arthritis in their hands. Yes I recommend.

THIS WORKS!!!
This little gizmo WORKS! I'm old, and my grip isn't what it used to be. I drink tea in 20 oz. bottles, and have come to the point of having to get someone to open them for me. This works. I can easily open them with this. The ability to open pop top cans also became soooo much easier. I would recommend this highly! 10 stars!!!!

Great opener
Finally got to use this the other day, does exactly what you’d expect it to do, took the strain out of opening a bottle of tomato sauce. Did the job, wish I’d bought on ages ago.

It is amazing product
I used it many times for medicine bottles where it would extremely tight once you try to open after a week. It is amazing, no pain but gain.
