Calculated Industries #1190 air shim inflatable pry bar and leveling tool; 300 lb rating; contractor-grade alignment pump wedge

Where is it made?

What are the dimension of the cushion, itself? Just the square part, not counting the pump aparatus, or the deflated thickness. Thanks

Is this good for when you get your keys lock in your car?

I need to lift my refrigerator to put some appliance rollers underneath. Can I use this to lift the entire refrigerator? Or maybe use two air shims?
