Very simple
It's very easy to setup. The only problem i ran into was the powersupply i tried using the cable it came with the cable was bad so i used one of my other cables and it works just fine. I did have to look up how to set it up on the internet but that was easy as well google brings it right up just type in how to setup nerd miner. Then scan the qr code to hook the miner to your phone

When everyone digs for gold, sell shovels
This is an excellent product "but" do not expect anything to happen, like they say it's a lottery ticket only, used for educational purposes, helps to understand the mining concept, in other words, Don’t dig for gold, sell shovels. and The secret to getting rich in a gold rush is selling picks. if you know what a mean.

Good product for beginners
Product does work and is mining; however, the only reason it is getting a 4 star is because, when opened, you can tell it was a returned unit. It does have visible scratches on the glass and it was already pre-assembled. Overall, these machines are good values for what you pay and very easy to connect for those new into the mining game. The design makes the screen easy to read and understand.

Low power, compact design, and well made.
This is the second generation of this device. If you are curious about what it is like to do solo mining at a low cost and with minimal power consumption, I recommend it. I had avoided the whole crypto field, and my curiosity got the best of me. Set up a wallet and configure this item, and you're all set.

No Support and instructions are not available
I bought two units, neither have worked, the setup is a nitemare and just try to find information to help get it working. Seems a complete waste of money and support is non-existent! I have been on this for 6 hours and I can not get it online even with rebooting several dozen times and starting over.

Defective
I think the one I got may be defective, after 2 days the screen is flickering and glitching.

Great little miner!
This is a really cool little unit. It was easy to set up and I was mining bitcoin within 20 minutes. The display is actually quite pleasing to look at and the quality is more than I’d expect at this price. It works as advertised and I really have nothing bad to say about it!
