I avoided getting the vent version because I live in FL and another reviewer said it would cause moisture to form in my phone because of the humidity (don't know if thats true but it sounded reasonable)

but I recommend getting the vent version

stick band is not 3M but a cheap version of it, does not stick even to a glass.

I order a more expensive version.

I gave one to my husband and he is v happy too.
