Summary: The product we received has a similar problem to several other reviews. The USB connection has a design flaw so it doesn't work and comes loose. So if you are able to rely completely on solar charging it may not be an issue, but we wanted to be able to use USB charging at least as a back up option.
Summary: Good sound, but doesn't charge very well via solar panels. The port for the usb charger wore out and won't charge anymore. I contacted the company about it and they never responded. Dissapointing.
Summary: Bought this for the deck, for outdoor listening. When ten feet away outside, you can barely make out what song is playing. This is with this volume all the the way up on my iPad and the speaker. The iPad4 I am using, and all my iPods, blast from headphones.
