has anyone ever tried these or anything like it?

I'm thinking this may be a cheap way to get seat warmer without taking apart my seats etc etc... but are these cheap
quality? do they work??? Would like to know cuz I would like to be warm for this winter.

i've tried something similar to that which i got as a gift a few years back. it heats up fine but i find it uncomfortable and the worst part is it adds an extra inch to your seating position and i'm just about border line touching the ceiling with my head normally.

hmm... comfort for warmth... that's such a tough one....

I DON'T KNOW WHAT TO TELL YOU. IT SEEMS LOOKS LIKE IT WONT STAY IN PLACE EVERYTIME YOU GET IN OR OUT YOUR CAR JUST LIKE ANY SET OF SEAT COVERS.
