My 45 just passed away after about 4 months. Completely dead. Nothing worked. I have contacted support. You will replace him. But it wasn't until I sent in the defective watch that they sold me back to them at my expense. They won't send me a replacement until they get the defective piece of crap they sold me. There is no excuse for this watch ($199!) ruining the bed after 4 months and no reason I have to pay to have this crappy watch sent back to them.
