Summary: This is a decent amplifier for the money. I purchased it to run a pair of outdoor speakers I mounted under the soffit of the house on our back patio and this amplifier serves its purpose and provides plenty of power to the speakers.
Works fine for my purpose although it is a real piece of junk

Summary: I read some reviews before my purchase. I think many people who wrote them were not technically proficient, as most were totally positive. A few were technically honest: this thing IS a piece of junk. It works just fine although the blue LEDs are really incredibly bright as everyone notes.
Summary: I bought this amplifier to boost audio from Mp3 players and YouTube videos in our church's youth classroom. It works extremely well for both purposes. We get plenty of amplification without any distortion. The separate bass and treble controls are a huge bonus.
Excerpt: I'm using it with a couple of old Bose Bookshelf speakers, in a 250 sf office. It won't crank really loud before distorting ( it seems more like a 2x 15w amp), and you'll want to make sure not to overdrive the input.
Summary: ***THIS REVIEW IS SOLELY ON THE PRODUCT. IN NO WAY DOES IT REFLECT ON AMAZON'S EXCELLENT CUSTOMER SERVICE*** Distorted sound, even at low volumes. Used it for two hours to power two speakers at 50w each, at low volume. Kept indoors, A/C on and we'll ventilated.
Summary: I have been using this to drive my bathroom built in speakers for 2 years now. I push it to the end. works great. this will never be an audiophiles dream but when the water is running you cant hear the little bit of hum it has at top volume and no input. I would buy this amp again.
