I'm absolutely disgusted with the fact that my watch which is supposed to be water resistant is now coming apart. The back sensor cover has come off and after reading multiple threads on it happening to them, I think this is a defect with Samsung that needs to be addressed. The cost of these devices are high enough that we should get the satisfaction of trusting they should last a while. I bought the device because I am a fitness freak and now I cannot even trust Samsung "ACTIVE" watch.
Do not buy this product.. I've read too many reviews of this happening to them.
