I supported the project on Kickstarter so I waited eagerly for a while to the my Turtleshell. The thing is surprisingly small and yet packs a punch. After charging it for the first time, all the while constantly examining it and discovering how bombproof and well built this thing is, I quickly paired it with my phone and cranked the beats. It throws noise everywhere in a room and outside, and with excellent full bodied sound and decent bass. Keep in mind the unit works exponentially better when it is placed on a flat hard surface facing up to throw the best sound and use natural acoustic reflexes. It will play nice and loud suspended on a mount nonetheless.
-definitely water resistant (stayed out on the field during soccer practice all the time playing tunes).
-Bombproof (have yet to think of a new thing to throw it at)
-Long lasting battery (7 loud hours in my experience)
-looks so darn neat, like a futuristic turtle shell, or somethin'
-Distorts bass when both speaker and music device have volume cranked!
-Only works most effective face up on a hard flat surface
-Bluetooth range drops quickly when battery is less than half (I just use aux cord by that point)
Bottom line... You neeed it, get one. Then kick it.
