There's the problem right there. At some point you're going to have to take it apart and then once more you're in the odd parts problem. I tell you, it's missing/extra small parts all the way down.
BTW on the subject of magnetic and LED lit gadgets there's loose screw picking up gadget. The LED shies through a little window which is built into the magnet. It picks up iron filings which cover the window and block the light. Nice idea in principle but once the it gets blocked it stays block. No way is the magnet going to release those filings.
