If you?re looking for an all around waist trainer to wear to work and the gym this is the one. Der Lagoon läßt sich sehr klein zusammenfalten. The advantage of smoothness, meanwhile, is that it looks superficially nicer. I need a replacement and when I sent for the second one received a completely different and dysfunctional product with no air, just a hard ball wrapped in soft plastic. Furthermore, if you are listening to music through your iPad or iPhone, it decides to insert little beeps for certain feedback notifications that never happen when you are just using your device without the speaker. At first I though that it must be a batch issue, but seems like even the predecessor non Bluetooth K371 had these issues and were addressed 4 months after the release. This rack was exactly what I needed to transport my 14 kayak. Wore barely half hr had to go barefoot Disappointed There is no descernable click or acknowledgedment that the speaker has done what you want, so one will hit the button twice to skip a song, instead only one button press will register and the speaker will pause. Fit a little large but still not unreasonablly large.
