NerdMiner V2 MAX Solo Bitcoin Miner – 930KH/s Hash Rate, 1.5W Power, 3.125 BTC Win3, Compact Design, 2.4G WiFi & Wired Connectivity, High-Efficiency Cryptocurrency Miner for Bitcoin Enthusiasts

Never managed to get it to work. Bought it just for a goof and thought it would be cool to have on my desk but seemed a lot harder to get setup than described. Could have just been me but I'm not giving myself a 1 star review. I'm a 5 star man all the way!! <-- If you don't watch Sunny In Philadelphia....you won't get that last part :)

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.

Easy set up let the lottery begin

Don’t even waste your time or money… hard to setup. Still don’t have mine set up. No support to help. Mine is stuck on the loading screen been there for days. Complete disappointment

Fun inexpensive way to get a lottery miner.

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!!!

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.
