Review: Buyers beware beware never get this product - They don’t even mind anything whatsoever they don’t provide a good platform for you to change it or adjust settings without resetting the device completely and then putting everything back in and even if you do have the right addresses and all that stuff it doesn’t let you go between it, your phone settings or web, web addresses without having to log right back in to it every time to adjust anything I will never buy a product from this company ever again. I’ve already salvaged chips and components for my own project, I repeat to all would be buyers of this product never ever ever ever ever ever ever ever buy it. It’s a waste of your money, even though they will refund you without having to have you ship the product back, which is the only good side to this Purchase. I will never ever buy it again or go through this company again.

## 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.
