It heats but no more ...

I installed it in my heated seat Ford Fiesta and it is easy to install; two hooks which pass under the seat with two straps that attach under the seat but the seat forward. So it looks to hold but actually after one week, the strips have frailties and the front ones were dropped (one torn). One of the two brackets also sold under the seat; to force up and down the car, the seat is found completely misaligned, separates from the driver's seat. In short, the product is not very successful and has design weaknesses which is rare on AMAZON products. For the heating portion, it quickly or too hot. You feel a tingling sensation in the thighs unpleasant. I keep it anyway, but I think that Amazon must rework the product.
