I wasn't expecting a lot of hashing from this little unit, but I was expecting some. I had also heard about how some cheap units were not real. I decided to give this a try. I logged it into a BTC pool so I could measure results. If it did what it was advertised to do, I was going to pick up several. I was able to connect the unit to the pool. The pool even registered it and recognised the expected hash rate. However...it mined nothing....at all. I tested it for over 6 hours, and my other miners worked fine, while this one contributed nothing to the wallet. ... show more

Cool nano-miner! Works well. Support is responsive! No instructions on how to assemble, but easy enough to find information about this miner. Connected easily to Wi-Fi.

It works as should. Set up was easy if your familiar with how these work. Set up will be a bit difficult for first timers. The case isnt the best fit. I got it plain with the clear case and the cutout for the buttons and connectors doesnt match up no matter what orientation you put it, it will not match up like they hired a person who failed geometry to design this case but luckily the spacers gives it enough room to not interfere with anything. You just wont be able to reset or reboot without removing the clear case and ontop of that they forgot to cut the case out for the light sensor ... show more

Increadibly hard to get to mine. Need knowledge and how to connect to different pools to get to work. Very bad included instructions. Make you you look up a video for the correct device, not many out there as of this review.

    • Cheapest lottery miner on the market

This miner started my addiction. I’m not technologically savvy at all. I’m a Carburator and hammer person. But I did have this mining in a heliospool out of the box off my phone. You can monitor it in HashWatcher. Mine several different coins such as BCC. After I got my second miner I did update the firmware. Easier than expected. All you do is go to the website. Select the device and plug it it. ... show more

Hey fyi dont buy this product. I should have known, but as soon as I plugged in my computer, my motherboard,d after a week started to act out. My USBs would crash, disconnect rapidly, and just ruin my computer. If you buy, be cautious
