When the screen shows "short" where is the short? In the topper or in the PV? I've contacted Vapor Bank and after their first reply they are unwilling to help me out with this V3. Actually what they sold me as a V3 is a V2 by their own admission. Their policy on replacement is that you get 3 days and then you are SOL. Don't like them and am going to have to post a negative review in the Suppliers Forum.
