Air Wedge Bag,HTCELLE 3 Piece Commercial Grade Air Wedge Bag Pump Professional Leveling Kit & Alignment Tool Inflatable Air Wedge for a Variety of Jobs,Sizes/Small/Medium/Large.

We used these to work body dents out of a truck bed. flipped the bed upside down, and wedged these in between the corners of the outer panel and the inner frame... used it to push dents out as we hammered the edge of the dents with a deadblow from the outside. we managed to remove a 12" long 4" deep dent with them. The point is, they're EXTREMELY tough, and we were mashing the little pumps to the absolute MAX and they never failed. Pressed up against sharp corners in the frame and never nicked or cut or tore. Absolut units! I'll bet they're indestructible for their normal use of prying open a car door. I think you could lift heavy equipment with these to wedge other lifting equipment under them.

Great for aligning doors.

i got these without that stick thing and regret it. the bags work awesome tho. i use them for abunch of things other than getting into my car

Pros: -Hold air for long periods of time -Can lift heavy appliances like fridges and washing machines Cons: -Long one is not as useful at lifting appliances

These are very functional items - easy to use, strong, stable, and durable. The release valve is effective at locking air in, with no air release prior to using it - it works just like the air pressure cuff at the doctor. No power supply, just air and pressure. Good price for the set. They are a firm, medium thick, material so can withstand being shoved under what you need to lift - but are soft so they will not scratch anything. Easy to use and remove!
