It was super easy to install. Optisch sieht es sehr robust aus. It works but I dont feel comfortable using it without a spotter. Now my toe is close to the top and the width fits like a glove and I have a little wiggle room, more room if no sock is on. I honestly they look exactly like the Croc version, love them?? I ordered these waist beads to track my weight loss. Sound is okay, what youd expect from JBL signature sound, which for me is quite clear with all ranges, but the fullness of sound is too neat and tidy. I probably wont be buying anymore Kingston products if this is the lifespan of some of the key features I purchased for. Tengo también el modelo Powerlocus Grand Exclusive 5 y como esos me los ha quitado mi hija pues opté por comprarme otra vez de la misma marca pero esta vez el nuevo modelo P3. Nothing is explained about how it all began, either.
