Query: Works well

I got this a few days ago. I immediately tested it on two Super Nintendo games and one Game Boy Color game. All 3 fit this tool perfectly and opened without any trouble. No wear and tear on the bit, either.If you want to replace a battery on a GBC or SNES game, this works great. It would've saved me a lot of trouble if I had this before replacing the battery in Pokemon Silver.Don't know if the seller matters much, but I got mine from Lukie Games and its in great condition.
