NerdMiner V2 Ultra 300KH/S T Display S3 Bitcoin Miner with Low Power Consumption Crypto Nerdminer with Fan Lucky Miner

This miner is like a slot machine, but with more tech and less Vegas. It runs quietly in the background, crunching numbers and hoping for that sweet Bitcoin jackpot. Will you get rich? Who knows, but it sure beats watching cat videos while waiting for your fortune. Roll the digital dice! 💰💻🎰

Out of the box it wouldn't hash or submit shares. I checked my config and nothing was wrong. I erased it and installed a different firmware i know works. It of course worked with my custom firmware. Support sucks, they want you to call an "Engineer" on WhatsApp. Tried to get them to provide me a copy of their firmware but they wouldn't unless i call. Just buy one of the S3 displays for $20 and flash yourself.

It is really "toy". They are referred to as "lotto miners". Too much hash on network for these to find a Bitcoin. Don't bother with this model. The fan doesn't really help. In fact, it has started to stick and make noise.

Needs zero stars, trash.

As described

Worked for one day and quit connecting to the pools and my bitcoin wallet…

maybe if it was cheaper it'd be worth it but these little things don't do anything besides teach you how to set up an actual crypto miner and draw energy. the chance of one of these things securing a crypto block is so close to zero that you'd have a better shot getting struck by lightning twice. before you get your hopes up some solo mining websites will tell you to not even use these devices on their service because it does nothing but take up bandwidth.

Easy to set up

Pretty much a fun toy, doesnt really do much, except maybe give you a better understanding of how hash rates work etc. This device actually stopped working after 3 days of use.

The device seems well constructed and there were no broken or loose connections inside the case and the 3d printed case fits together surprisingly well, but the only thing that seems to work as intended is the fan, the set-up took 27 attempts to get it to save the settings, and since then still won't connect to WiFi or update it's screen. Set up has been redone and saved a total of 5 times now,the device has been reset 3 times of those 5 and completely reflashed/updated the other 2 times and still won't do its intended job.
