My old former seat pad was no longer needed, because I repeatedly blew the relevant car fuse and thus no longer working properly and every time the affected fuse had to be replaced. The new Dino-reviewed here cushion replaces the former old. This makes them good. It warms more slowly in the first heating step and correspondingly faster in the 2nd heating stage. The coating material has excellent tactile feel, it feels good. The plug for the 12 volt outlet is very high quality and has a red indicator light integrated operation. But what must be regarded as not so advantageous, are the 4 very small hook for securing the seat pad to the car seat. Good that I had cut off the old much larger attachment hooks precaution and thus could use in addition. Therefore, a star deduction.
