I bought one of the pink electric massagers off of ebay. For anyone who has used it, I was wondering if there are supposed to be bars or power notches on side of the screen, because I dont see anything when I press up or down, I cant tell what speed or intensity it's at. From what I've read in other threads I think mine might not be working right.. unless I'm confused by all the buttons still. Any help with this would be great. Thanks. :)
