    • A good buy that is budget friendly.
Love the smaller size. It puts out quite a wallop in sound, with no distortion at higher volumes. Well built, with power to spare. I like that it comes with a remote. Budget friendly for consumers who are looking to get quality merchandise.

    • It's cute, and tiny, and what a bang for the buck.
This item is exactly as advertised, and more. The sound is absolutely amazing for this little midget stereo. My son who is an IT specialist with a national corporation, and after hearing what this little baby can do he immediately got online and ordered both the speaker and this little stereo receiver for his own use in his home office. every feature, including the ECHO AND DELAY AND BLUETOOTH WORK WITHOUT ANY ISSUES. The remote is very sensitive, and all the feature work unfailingly! Both myself, my wife and our son all love this item. for the price you just can't go wrong. I don't just hand out good reviews, and were this item not up to par, I'd certainly tell you about it. It is a great unit and I know that anybody that buys this won't be disappointed, and besides all the wonderful technical stuff, it's absolutely cute to look at, and very visually appealing for those that like that type of feature. The treble and bass features are astounding for the price, and the volume, well I can't turn it up beyond 6 inside, or I'd probably deafen myself, no joke. ... show more

    • FM tuner needs to be better
It's a nice receiver but you can't tune the fm receiver to a specific station. You have to scan then run through all the presets. And in my case the station wasn't strong enough to get picked up by the scan

    • A lot of power and features for a small, inexpensive amp. I'm impressed!
I love this little amp. I have a smaller version too but needed this one for the fiber optic input. It's kind of amazing that you get a fiber input on a product at this price point. Sound is remarkabke for such a small amp (Class D magic). It has several other inputs and even includes two mic inputs. I haven't used those but I could see where this could be useful to set up a mini PA system for public speaking. This amp only has one set of speaker outputs, but that would be the only thing I would point out. The bluetooth is easy to connect and with any decent set of speakers the sound is surprisingly clear and loud. ... show more
