Review (4/5): Works Great on Certain Vehicles
For some reason, these just don't work so good on my own car. They'd get all deformed and stuff. I had to purchase a sturdier hard-plastic adjuster for my car (and even that one didn't work right until I sealed the snap with krazy glue).
But I drive a minibus at work, and these ones work perfectly there! Go figure.
I'm always losing them, so I think I've bought like 15 or 20 so far.
