Dynamite comes in small packages! This has enough power to push my 2 10in Cerwin Vega speakers just like as good or maybe better than my older Sony receiver. I finally bit the bullet and took a leap of faith after seeing mixed reviews. Its definitely a space saver and I couldn't be more pleased with the sound quality and how compact it is! Price was fair, Bluetooth works like it should, the remote has decent range and works fine!

I give it a 5 star because it's perfect for your room, or the garrage, or backyard it's pretty loud. The sound is good. USB is good, it has radio rew- ff and repeat. Blue tooth is also good. Comes with control My husband is a device guy. He says for the price it's a good price for the device. We also add a equalizer.

Does its job. Keep in mind the bass quality isn’t very good but it’s very fairly good value for your money. Its blue lights are also a nice touch.

This is truly a great product. I bought to increase the sound out of a TV I had on my deck as it was above my hot tub. When the jets were on I could not hear the sound until I hooked this puppy up. I have two outdoor Polk Audio Atrium speakers but needed something to power them. This did the trick. I hooked up to it with an optical cable and was able to run normal speaker wires to the Outdoor speakers (which not any tv's i know of have). They sound great. One trick, change your Optical out sound to use PCM and it then works like a champ. I zipped tie 'ed the unit to the back of the TV and you cant even tell its there.

I purchased this based on a mixture of reviews. My amp stopped working and I wanted a cheap and quick fix. I give this a rating of 3 because of a list of pros and cons via my experience versus expectations. 1. Consider the price. You get what you pay for, however.... 2. I hooked it up to a pair of 10" Onkyo 3-way tower speakers. Now, its not my Onkyo amp, about 1/3 the volume. But, I was shocked at the sound this tiny lightweight amp puts out. But it is not 200w. Lol. Maybe 50w. 3. Other reviews report static. This is true, however you only hear it when not playing music and if you are really listening for the static. 4. Radio has a built in antenna. No range at all. And it is very confusing to use so if you want radio, don't bother. 5. It is Bluetooth. It connected very quickly and with not issues. But the pictures showed a fiber optic input as well. This is NOT AN AVAILABLE OPTION. Part of my disappointment. 6. Comes with a remote that works oddly. There is a power switch, not a button, so the remote can not completely turn the unit off. Its a sleep mode but you can still hear that the speakers are receiving power. And the volume on the remote has some sort of volume limiting compacity. It's weird and hard to explain. But the knobs on the unit work properly. Overall, I'm satisfied. For the price I feel like I did ok for an emergency fix. Hey, I'm listening to it now and jamming.

Ok update... They took back original and sent replacement, Now that I have a remote and can go though all the options I have tried it out. Works well in all modes except the one everyone has trouble with. FM Reception. on the 1 local station it does get the sound is great. But I don't like this station. All other are 50 miles plus. But great unit for price and space it doesn't take up.

This is a decent amp for the price. And I love that it is so small. Bluetooth connectivity works reasonable well. I did not test the remote control or radio frequencies. I am going to return it because it has a fatal flaw. There is a loud hum/hiss/background noise when the unit is on. You can somewhat mask it when the music is playing loud, but otherwise it is extremely noticeable. Other reviewers had mentioned this problem, but I did not realize how bad it is.
