I had them on my E92 335i for my small pup. Worked great.
Install/uninstall takes about 5 mins top after 2 times use.
Even though it's somewhat bulky, it comes with nice storage bag with handle which actually helps the covers stay cleans while not in use.
It's a bit pricy but works best. So I got one for my E90 M3 now.
