Had this for 2 months now, still running and still have yet to hit a block. Super easy set up with an app and Wi-Fi makes this very easy to place. Noise level is as advertised, very slight humming during the night nothing more. Good as a mini heater you can place in front of you.

Works like a charm stays steady at 6.7 I never have to mess with it and the app helps out a lot !!! It does get a little hot if you run on high constantly but I use fans without any problems !!!

This unit worked great for about 14 months. Kept the filter cleared. Not in a high heat/humidity area. Was plugged into a surge protector, recovered from minor power blips here at the house. Until two days ago. House power went off for about 1 second then came back on. After resetting the clock on the microwave, noticed that this unit did not power back on. Tried unplugging the power unit for several hours and then plugging it all back in. Nothing. The unit has completely died after less than 15 months. Should have lasted longer.

Tucked into the **entertainment center of my game room**, the **Canaan Avalon Nano 3S** is the ultimate **lottery miner**—and I’m here for the long-shot thrill. It’s not about steady profits; it’s about the dream of hitting a block while I’m speeding to win in Nascar '25. **Three speed settings keep the odds flexible.** Eco for stealth mode, Normal for daily spins, Turbo when I want max entries into the lottery. Switching is a single button on the unit—no app, no fuss. **It heats the game room like a cozy side bet.** That 120 sq ft space stays toasty from the gentle warmth radiating off the middle shelf. It’s free heat with every hash, turning electricity into comfort *and* a chance at BTC or BCH. **Dead quiet—perfect for late-night lottery runs.** Even on Turbo, it’s a soft murmur. No fan noise to wake the household or interrupt a clutch moment. **130 W max for a true lottery ticket.** At full tilt it sips ~130 W while throwing terahash at the network. Pool mining? You’ll make pennies—literally. But flip it to **solo or group mine BTC or BCH**, and every hash is a scratch-off. One block = life-changing. The price-per-TH is absurdly low, so the ticket costs less than a latte. Real talk: **you won’t get rich pool mining**. This is a **lottery miner**—plug it in, choose your coin (BTC or BCH), pick solo or small group, and let it run 24/7 from the entertainment center. If the hash gods smile, you’re set. If not, you’ve got a silent, efficient space heater that paid for itself in vibes. The **Avalon Nano 3S** is the most fun I’ve had with a miner that doesn’t pretend to be a cash machine. It’s hope in a box—and it keeps my game room warm while I wait for the jackpot.

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.

I’m pretty impressed with this little miner. I have it in a pool and it is performing better than expected and a bit above advertised.

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.
