NerdMiner V2 Ultra 250KH/S T Display S3 Bitcoin Miner with Low Energy Consumption Crypto Nerdminer with Fan Happy Miner Win 6.25 BTC (Orange)

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.

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! 💰💻🎰

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.

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.
