Amazing product - so easy to use, so easy to mine... also can keep you warm... I bought 4 of these!

Amazingly quiet even on “high” mode. Like the air filter and report on when it needs to be cleaned (percentage). Has external power supply that gets quite warm but unit itself does awesome job of removing heat off the ASICs. Case is barely above room temperature. Used Google to find some helpful setup videos.

If the software was better, this would get 5 stars. The miner itself works like a champ but don't expect the power supply to last long if you constantly run this in high mode. High mode draws approximately 130-132 watts from a power supply rated to 140w. The supply gets pretty warm to the touch so I have been running this in Medium mode (approx 5.1 th/s) The Avalon app for your phone is pretty limited in what you can do with it and the web page pretty much just gives you basic stats on the miner and the ability to edit your pool info. You do not have the ability with the app nor the web page to view the mining logs Perhaps they will implement the ability to view the runtime logs in the future. While I think this is a really good piece of hardware, I think my next home miner purchase will be a rev 6 nerdQaxe +++ rated for 6 th/s @100 watts.

Amazing. So here's the math. I have owned several miners in the past. I stopped mining after the last halving running a S19j XP which is a generation 7 miner @ 3370 watts. It was extremely loud and get extremely hot. This is a generation 8 miner. It runs at 134 watts on high power. I can barely hear it running. It does get warm. Power supply is hitting 123⁰ F. Actual unit 160⁰ F internal. Exhausting 80⁰ F, but I cant feel the exhaust over about 16" away. Installation was not terrible. The little SIM eject key is for the Factory Reset, which I did have to do because I messed up the password a couple time. The Avalon app is not terrible, but I would also like the option to use the IP address, which is not an option at all. It just pops up a QR code to force you to use the App. In 15 minutes I was hashing at 6.6TH/s. Now that I not going to make you a millionaire, probably ever, but at such low power consumption, this is a heck of a deal for simple home mining.

I ordered one in September 2025 and upon receipt could tell the inside of the box had been opened and tampered with. The Wifi dongle was not the original and was replaced with a dongle that had the identifying information physically scrapped off. The warranty date in the app showed that the unit was originally opened and activated in June 2025. I returned this one and received a replacement. The replacement had the exact same issues as the original and I returned it for a refund.

Very easy to set up and very reliable. It runs consistently at 6.5 terahash and sometimes as high as nine. I do wish there was more info in the app and web interface and the ability to do upgrades and overclocking. But admittedly, it makes it much easier and less stressful just to plug it in mine without worrying about overheating and having to adjust things. Gives off a pretty good amount of heat too if you want to keep your feet or hands warm while you're working at the desk

Received the Nano 3S within 24 hours of ordering. This is a must have for the enthusiast miner. Put it to work and in the first 24 hours it brought in over $.75 for the first day pool on ViaBtc. For 6 TH mining BCH, that amazing. Thank you guys. I’ll buy my fourth from you very soon soon!
