I always wanted one of these, but now I have 2. Yes, they come in a pack of 2. I'd never seen the rectangular ones before. All I've seen was the round ones. This seems a lot more useful for longer parts like drill bits. If you look at one of my photos, you can see I fit a whole set of spade bits and my drill press chuck key on it. Really handy! This is also handy of course if you're working on your car and you want to hold nuts and bolts or sockets that you're using. You know how they tend to fall into the engine, never to be seen again. Probably the source of nuts and bolts on the highways after they shake out. It will stick on vertically too, so you can put your lug nuts in it when removing a wheel. Each tray has two pretty powerful magnets and they're covered with a rubber or plastic coating that won't mar your car's paint. It has a chrome finish to resist rust and a lifetime warranty.
Pros: Durable, Easy to Use, Long-Lasting, Strong, Sturdy
Cons: i didn't get one sooner.
