Bests & Worsts Reviews from Amazon

Worked well while it worked, but God help you if the batteries die. One of the ridiculously cheap screws stripped out immediately and I couldn't get it open. I tried everything, including finally trying to pry it open. Nada. It went in the trash. I don't understand why manufacturers use such cheap screws? What are they saving, half a cent? If a screws can't be screwed and unscrewed multiple times you might as well rivet the thing shut and make it disposable - which is what mine turned out to be.
