The material is soft and comfortable to sit on.
Installation of seats is quick and easy. The straps are quickly lashed to the car seat. Perfect fit and no slipping.
The heat output is super. After one minute before starting the cozy warmth.
The seat and the backrest can be separated with the manual switch in 2-temperature settings
(High and low) are turned on from each other.
Unfortunately I have to give a point deduction, because the connector for the 12V cigarette lighter sits a bit shaky. But everything else is great!
