This thing doesnt work the way I expected it to, but my husband loves it. It ends up looking like a Swiss army knife. It was complicated to put together, but the seller sent tips and instructions. Im not sorry we bought it, but not sure Id buy one for myself. We weren't able to fit several of our keys in it because they're bigger. I didn't really think that through when ordering. But if you have a bunch of house-type keys or smaller, its a handy little gadget.
