Calculated Industries 1132 AirShim Inflatable Pry Bars and Leveling Tools 4-pc Value Pack – 2 Original AirShims, 1 AirShim Pro XL, and 1 AirShim Slim | Contractor-Grade Pump Wedges | Set of 4

I expected these little bags to do some lifting but I was impressed at how much weight they can lift. They also seem to be made of a higher quality material that does not tear and can be used again and again over the years.

These have never failed and were a fantastic addition to my DIY projects around the house. It’s especially helpful for leveling doors before fastening, making the job much easier. The quality is excellent, and the four-piece value pack offers great versatility.

Work great and well worth the price; other places sell one (2) for the same price I got 4.

Wish I had these sooner in life, nonetheless they're amazing. From being able to slightly lift any heavy object to spreading doors and using as temporary shim, they simply perform when you need them to. The variety pack is where it's at..so far I've used all the sizes with no issues and fits in tight spaces.

saw a review of these (not this brand) in the New York Times and decided to get some for my toolbox. I haven't had to use them yet, but they are definitely cool, and I imagine they would be great to have on hand in an emergency. AT this price, it is better to have them, for if you need them, then need them and not have them.

It was second purchase, well made and do the jobs

I needed to slightly lift a very heavy washer/dryer combined unit. The weight of the unit is roughly 380 lbs. These were much more effective than I expected. I had to use an item of this type because the washer/dryer unit is in a very small space. These were effective at lifting the unit a few inches. That allowed me to place gliders under the feet so that I could move the unit around. Well worth the price.

i was looking for something like this. i needed to move, lift, and level a very heavy executive desk and had no help. these were perfect for the job, though you do need to use small firm pieces of wood or something similar to give them a stable platform. there is a little bit of a learning curve to find the best way to use them. i was able to raise it 2 inches with no marring or damage to the desk. take your time and don't get discouraged and you will like this tool. they are sturdy and made strong. a good product. i would buy it again.
