Ive been wearing this w736 every night since I got it and the vibe alarm wakes me every morning. Im really surprised how strong the vibration is.
I made a $14 offer for a pre-owned model with blue case and the seller accepted. It doesnt look like its been worn much if any at all. I really want it to have an extra strap, etc. and plan to take the module apart to see how robust this model is constructed. Should have it in about a week.
