I replaced my older MegaBoom with this smaller unit for travel. I like that it's smaller, less bulky and less weight. The sound in the hotel rooms I stay in is great.

Sounds excellent!
I use this speaker all the time. It's great to bring around with me when I'm working around the house. I got a second one to pair them together. The battery lasts a long time, it's easy to charge, and, as an audiophile that is constantly listening to music, I love that I can take this outside while I garden or have it in my bathroom or do anything, really.
