I got myself one of these off of Woot a little while ago. I think I got it for around $150? Might have been a lot less. Either way, it was money well spent.
I use this daily at work and the most incredible thing is how loud and full the sound is for the size of the unit. The downside would be that it has to be plugged in, there is no battery option. And getting the hang of the remote took a little getting used to (the remote itself is good, but I had some issues initially getting it to work with my phone - I think it was a timing thing for when I started the app and when I was using the screen vs the remote, it works great now though).
The remote works pretty well but doesn't work fully with all my apps. It works fully with the default music player on the phone, and also with the audiogalaxy app. It doesn't work with iRadio fully. I can't seem to get it to pause, but it does adjust the volume and you can skip back and forwards the same you could by pressing some of the buttons on the screen.
Overall, this is a great value and that's mainly because of one factor - the sound quality for the price, and for the size is just fantastic. The only complaint, and this is being really picky, I would have about the sound would be that it's fairly unidirectional, it projects sound best towards where the speakers are facing, it's not going to be as loud if you're standing behind the speakers.... but I don't know how true that is of other units... so maybe this is a regular thing. I don't think you could ask for a sound this great for this price, and also have it be omnidirectional.
