Love them. Makes parking much easier.
Front camera is great too (only on the M3, didn't have it on the others; was too cheap before lol)
I also have an Alekshop front and rear camera setup on my E92. It works great and has been trouble free. I would recommend having it professionally installed as you do need to tear apart the dash to install it.
