NerdMiner V2 MAX Solo Miner 400KH/s, Crypto Bitcoin Miner Machine 1.5W Mini Miner Win 6.25 BTC Nerdminer 2.4G WiFi Connection（Blue

This thing is NOT what it says it is! At first when opening it only has a micro usb connection. Went through all the "setup" instructions and.... nothing wasn't connecting or anything. After looking at it further the case is obviously a cheap 3d printed case that is easily removable. Upon opening... there it was the advertised usb c connection. After several hours and almost chucking the thing out into the street I found instructions online on how to flash the chip with a legit nerd miner binary code. After some rotary tool work on the case to allow me to use the USBC connection I was finally able to setup everything am getting an average of about 55 k/Hs. Unless you have the knowledge to flash the chip on it I recommend staying away from this!!!

I think this is a great little tool for solo mining. You aren't likely to get rich, but they are fun to play with. They are very easy to set up and to add your own bitcoin wallet address. I have 5 so far and am hashing at over 5 million kH per second. you do need to update the software yourself for maximum hashes. Use flash.nmminer.com for the latest version, as of today I'm on 1.7.02. Even tough I bought them one at at a time, they all came very quickly, overnight in most cases. In closing, I love these things and would buy more if they cost a little less.

First, it's micro usb (5 pin) not USB C.Second, I'm no hacker genius but now that it's here, I just don't think I trust it not to send all my router data to the *** and then also divert whatever bitcoin I might win straight to their account instead of mine. I'd need to a lot more credible reviews and tests of the product before I use it.
