Glass Suction Cups,8"vacuum Cup 662 lbs Load Capacity Powerful Industrial Glass Suction Cups for Lifting Large Glass Tile Granite,Includes Carrying Case(2pack)

Works great.

Parecen excelentes mañana las voy a estrenar a ver cómo funcionan

Product failure Do Not Buy!Had both cups on a window that was less then 75lbs, both cups failed at the same time, destroying the window.I've used the Woods cups for years with no problems. Do not cheap out on cups!

So far they work great and are holding up well

so far, so good, these cups work perfeeectly

I've been doing some tile repairs using these suctions cups and they are helping me carry and place the tiles. Once the suction has a grip, the suction power is very strong and secure. I have not picked up anything over 50lbs so far, however I feel they can handle a lot more weight. I'm never going to try them on a 662lb load or even a couple hundred pounds if the item is highly valuable. But for my everyday needs they work great. It does take two hands to create the suction. One hand to hold the cup to the item being picked up and the other hand to pump the suction cup. I only need to pump 2-3 times for my usage. To release, press the red release button. I like the cup caps for protection. The case, although useful is a joke, the case is thin and flimsy, and the latches are beyond cheap. I'm going to add a Velcro strap. For functionality and quality vs price It's a solid 4 stars.

Excellent trabajo.

I thought I had a winner here. They worked great the first time I used them, They made lifting up pavers much easier. Several months later when I needed them on another job, they wouldn't work any more. Very disappointed.
