Replace the batteries often enough and this battery cover will soon come off. Opens only 45 degrees - and that's it. The first set of batteries is very difficult to insert and almost impossible to remove. I really felt like breaking the battery cover. Please note that the seller's penultimate product photo shows the battery cover is torn off and missing. ADVANTAGES: Easy programming, even with poorly translated manuals. Lies comfortably in the hand. CONS: Battery cover doesn't open very far and barely snaps (opens only 0.7mm) Programming changes when batteries are removed and replaced.
