I'd seen not great reviews about these Chinese-made copies of the Swiss-made tools, but they're working perfectly for me. No issues with loose bits, broken tips, etc. For what I'm using them for (changing batteries that have screw-down connectors), they're perfectly fine. Plus they're dirt cheap.

They're not as nice a the few Swiss-made tools I have, but my Swiss tweezers cost nearly $50. These were about $10, if I remember correctly. Also, keep a small magnet handy to magnetize them, so you don't drop the tiny screws.
