So I wanted something small, powerful, that can charge a device like a phone or my projector at the same time with good battery life. I've tried JBL, 2 different QFX PBX series speakers, JLab, JAM XTERIOR and others. Most where much larger (some 4X larger) in size but some smaller. This speaker blows them all away. The sound is incredible and loud. Even at full volume it's clear. I compared them with the THX sound tests, the Dolby Atmos tests and the Bose sound tests. It was every bit as good as the larger more expensive speakers and with very good separation. I wanted something that could go camping, to ball practice and be used in the backyard for movies but in a small manageable package with Bluetooth. This is it. I personally haven't had any problems with the radio like others. Maybe we have stronger signals or less interference here in the Dallas area. I have used it with my Motorola Z2 phone, my Andriod tablet and my AAXA P4X Android portable pico projector. So now I am totally wireless with portable entertainment. Another nice feature is that the top surface is flat unlike some other speakers so you can set your device on there or in my case, my projector. It's my personal opinion for my needs, the price is amazing compared to other speakers, Sound quality - Excellent, Volume - Excellent, Price - Excellent, Size - Excellent, Features - Excellent.
It's hard to believe this little box can make all that noise. I love it.
Sorry for the long review, but I was trying to find an in depth review when I was researching but really didn't find one so I just went ahead and bought it to try it out. I'm done searching. This one is it.
