These are not your ordinary suction cups.
I also have a bike rack made from the same suction cups from a different company (Seasucker).
They have a pump on the suction cup you use to create the vacuum. It has an indicator on it that will show if it is losing suction. It does say to let it sit for a few minutes before putting the TV on it to be sure you have a good seal, but I've never had a problem.
The last time we used it, we put the TV away but forgot to remove the mount. It traveled home, sat there for two weeks, traveled to our next camp site, and THEN i noticed we'd forgotten to take it off. Still had good suction.
If I trust two $6,000.00 mountain bikes on the roof of my car with it, I can trust it with a TV worth a couple hundred dollars max.
