Review: Won't load or log in! - Can't give a zero review!! First, it was supposed to be next day...a week later.. then the case looked like someone opened it, it literally popped off as i was putting it in the port. I didn't care really, more ventilation. Went through the standard setup process and let it run. Next day, check up online, i see my other 3 miners and not this one. It stalled at 80% loading up. Tried again with a different mining site, same thing. Did this way to many times!! Let it sit overnight unplugged, same thing again. Tried all the reprogramming and update sets, nothing works. Sending back for a replacement, going to give it 1 more try. Not impressed at all!! Bought cheaper ones with better results!
Review: Cool Bitcoin Miner - Set up in just a few minutes. Works perfectly as described. Mining away!

## Questions & Answers

**Q: Do I need a computer or extra equipment for mining?**
A: No extra equipment is needed! Only a USB power supply (5V-3A) and a WiFi network are required. It takes only 3 steps to set up, making it easy for beginners.

**Q: Do I need multiple power supplies when using multiple miners?**
A: It supports chaining multiple bitcoin miners, requiring only one 5V-3A power supply. Hash rate is cumulative, and wiring is simple, resulting in very low deployment costs for multiple units.

**Q: How do I manage multiple solo miners?**
A: Through the official NMTech NMController tool (Windows client requires .NET Framework, web version requires Python environment), you can monitor hash rate, voltage, and operating status in real-time within the local area network.

**Q: Does the firmware need activation? What if I lose it?**
A: No activation required! The firmware can be downloaded from GitHub (NMminer1024) or the web-flash tool. If lost, it can be restored with one click using the tool, without any extra cost.
