2026 FLAGSHIP NEW PRODUCT Review: Initially disappointed BUT then loved em. - Wouldn't stick at first BUT worked great when I wetted the entire suction cup. Pressed down in the middle for 10 seconds and then still pressing down tightened clamp. Worked beautifully. Initially disappointed but then loved these things after learning how to work em. Review: Worked well - Worked as intended. Just remember to use a little water on the suction cup so that the seal will hold.

Worked well
Worked as intended. Just remember to use a little water on the suction cup so that the seal will hold.

Great idea bad product
Suction cups do not hold I have cleaned my windows with Windex and still does not hold. I guess you get what you pay for. Not happy.

Held rear windshield in place for convertible repair
Did a pretty good job holding read windshield in place for glue repair. Sometimes wouldn't cling well after first use.

Works well and saved my window
These were a life saver when I needed to reseal my convertible rear window. The suction cups don't like to stick after a couple uses though and one tore already so I wish the suction cups were more durable but overall easy to use and good value. I would buy again but wish for thicker suction cups

Worked well. Found that I actually could have used more to cover the whole window with even enough pressure. But they did work as advertised.
