Works well as described, but the app is sketchy.

Works like a champ with very good power and sound quality
Very impressed with performance. It said to download an app from google play but i never did......It showed up in my Bluetooth scanning and paired instantly. I would advise using 24V power as the sound volume difference is noticeable. I just used 2 12v 36w watt adapters from some old cable boxes i returned and wired in a series to produce 24v......for such a small amp it has nice power and clarity. Using it for my pool speakers but might buy a more powerful module and build me a boom box.

Looks and works good but didnt come with instructions to put it together. Im running it at 18v 2A and at full volume it does get hot but not sire if thats something to worry about yet

Good sound for the money, but the current app is broken.
Bluetooth works fine & the range is decent. The sound is good for an amp at this price. The default setting is lacking on the low end, but you can tweak the EQ with the app. Right?There's where the problems start. The instructions are useless. The current version of the app doesn't seem to work at all. Installed & on launch you get a splash screen, then nothing.I searched around & found an old version that let me change the EQ & Bluetooth name, which was the main selling point for me. What finally worked was connecting to "Wuzhi Audio App" from the "add device" option in the app.If they can fix the Play Store app issues & put a little more effort into the instructions, this would be a 4/5 star product.
