Query: High quality but requires fogless spray.

The construction of the mirror is great. The suction cups keep in in place without issue. The fogless quality however is a bit questionable. It works good when used with the fogless spray, but without spray, it fogs up like any other mirror. The mirror needs to be sprayed with fogless spray every time it is used in order to keep it clear.
