I had it cranked pretty hard for about 15 minutes and no issues really. Not related to the 15 minutes it has sort of a New car smell but worse and it’s a bit Strong so maybe let it air out😂 I am not sure about the longevity The volume knobs have a smooth turn with a speed limiter it almost feels Super SMOOTH buttons are a bit clunky. Would recommend👏👏👏👏👏 and The Bluetooth connectivity does about 100 feet👏 ### ⭐⭐⭐⭐⭐ Amazing value! Flawless simplicity and functionality! *by C***S on Reviewed in the United States on 23 July 2023* The media could not be loaded.  Fictionally is flawless. So easy to operate! Press the power button and it turns on to either Bluetooth or auxillary, whichever it was left on previously. No turn on pop if I recall, and almost no turn off pop. I'm powering this with a 12v 3A Motorola cable box power supply. Although not a large amount of output power, it does play the 6.5" outdoor speakers I connected it to very well. They are connected through an outdoor volume color too, which works just fine with this amp. The Bluetooth range was also good. In my experience, it's similar to a portable Bluetooth speaker. So here are the compromises... power output isn't as loud as say, the $25 non-Bluetooth mini amps... sounds quality isn't as good as those amps either. Not that it sounds bad, it's just not as good as a 3118 TI based amplifier... and of course it's quite a bit lower than a Tripath based amplifier. Where this excels however, is in it's flawlessly simple functionally and it's simply ridiculous low price! ### ⭐⭐⭐⭐⭐ Easy to set up *by A***R on Reviewed in the United States on 12 June 2023* I may have crossed wires on my old amp and needed something fast. I was surprised at the difference in sound quality as well as how fast blue tooth connects. It is being used for a portable cooler with speakers built in and can’t wait to take it to the beach.
