Query: Worse product I ever spent money on&#65533;..

Cover broke after 3 months; the battery falls out too way to easy.It's a bad engineering design. Customer service has a backlog of cover replacements. It is plastic and its on the flimsy side, the device is essentially worthless and now my unit is sitting on my desk gathering dust now.I had called, wrote and emailed customer service numerous times for months with no response. I'm sure I'll buy never buy another one of these or any products made by/from Oregon Scientific the way they treat their customer base.Recommendations: Stay away from it, Buyer beware. Don't waste your money!
