not recommended for Imac

1) it is quite possible to overcome the magnetic force and to solve the windscreen
2.) the force does not last long, I do not, the disc then fell down and then damaged my kitchen table.
3.) the windshield is just as loose with his fingernails, the siphon are superfluous.
4.) I still have an ugly impression of the siphon on the windshield, which I but considers that, in an extensive cleaning can remove the impression.

I would not buy again!
