My company purchased 8 of these for installing glass architectural wall product and they work great. We use them to move and position very large, heavy sheets of up to 1/2" glass, weighing up to 400-500 lbs. With two men and 4 of these grips we have no problem. They suction to the glass with ease and release with ease, and they are very sturdy and have strong grip. They each come in their own plastic hard case for storage which is nice, because once they are damaged you pretty much have to…

I used this to help install a frameless door for a bathtub. The glass weighed 90 lbs. and I had no problem picking it up with just one suction cup. Nice product and hard case.

My use is somewhat unorthodox. I am using it as a aid in pulling myself into a truck. I attach it to the inside truck roof (metal) and pull myself up into the seat. This is my second one I purchased. For at test, I stuck it on the side of our oven and even after 2 days with the redline showing we could not budge it!

Challange: Lift 205 lbs marble table top from garage to second floor kitchenDifficulty: HighObstacle: narrow staircase with 90 degree turnExtra Equipment: Dolly and GlovesOverall: Handles were a game changer in lifting it up to the kitchen. They offered more control and comfortability.

Moved a 75gal aquarium with 3 inches or gravel and 4 inches of water with no problems. Also moved a 55gal and 29gal. That's my feedback!

these work good , purchased a bunch of them for glass company only had problem with one going bad but the mfg replaced it right away

These are awesome! Excellent for all types of glass, in all shapes. Windows are a snap to install. Great product! The suction cup may not be able to provide a good visual indication of its suction strength or performance!

I bought 4 of these to move a 180 gallon, 400 pound glass aquarium. I placed them on the glass, gave each one a couple pumps and they were ready to go. The hold was strong and solid. I really wish I had bought these a long time ago. It really made moving my large aquarium a very easy task.

Worked out perfectly. Move a 250lb. shower door with two of us. No slipping. Did have a bit of a hard time getting one to release. May have been operator error.

Very sturdy, very strong, very well made. We remove and install windows and this thing is a beast! Very highly recommend.

I have to install 18 windows. I had bought the cheaper ones without the plunger and let's just say they lack holding power. I picked up this unit(and a different brand of the same size-they appear identical apart from the box). These things are nice! I had to bring two windows to the second floor and the stairs are not yet installed. We tied a rope around one of these and hoisted. No broken windows. They held firmly.

Works great. One of my new favorite tools. I do tile on walls and floors. This is a great tool for controlling the tiles above your head or even to adjust on the floor. I will be getting another one real soon!

Likes include each on comes in a case, with great instructions. They work great for setting windows on window replacement jobs. Much better than trying to hold the window by the frame especially if it has a bead of caulking on the fin or shims sitting in the sill that could get knocked off.

The suction cup works exactly as it should. It has good suction and plenty of holding power. Great for moving plates of glass and metal.

Works well with ceramic tile, but the tile should be smooth. A rough finish it holds ok, but not as secure as the smooth tile or glass.Nice product.

We needed to load a bunch of windows. They were really heavy. This clever device made the job easy. Fast shipping was appreciated too. Thanks!

I spent 40 years in the glass trade and originally used the heavy rubber/brass cups for commercial work, and then transitioned to the then new lighter plastic cups that worked equally well.These are the next generation and while of lighter capability than before are still very good for all but the heaviest loads. I can readily reccomend this version which is sold at an amazingly low price!

Used 4 of these to move a 300 gallon aquarium into place in a clients apartment. It took 5 of use but got it done with the help of these cups. Easy to apply and detach once finished. Suction was very good in my option.
