Terrible. Actually a bunch of shit.

That's a big waste of money. There are no instructions. The item arrived with a defective capacitor. It also came in torn packaging and many of the ends and components were bent. Not good. A real bummer, I was looking forward to building my own audio amplifier. :(

Pros
  • Impressive
Cons
  • Speed

STAY AWAY! for amplifier

Terrible, no instructions, no information on power requirements for the unit, I started with a 12 volt 1 amp power supply, got only distortion and no beep! I bought 2 of these both didn't work. Can't believe it was just distortion and no beep, without a schematic I couldn't even fully test the board! Stay away from these devices!

Pros
  • cost-effective use, new high optimization NE5532 OP-AMP
Cons
  • There are other interesting options.
