Questions
Will the suction cup hold on my wall?
On smooth tile or glass, yes, clean and dry the spot first, because suction fails on soap film rather than on a bad cup. On textured or matte surfaces, use the three adhesive strips included.
Can I actually use the screen through it?
Yes. The front is a touch-compatible film, so swiping, pausing and answering all work with the phone sealed inside. Volume is on external buttons.
Will my phone fit?
Most standard smartphones fit. Very large phones in thick protective cases will not, take the case off first.
Is the speaker loud enough over the shower?
Yes for speech and music. It is a small sealed speaker, so treat it as convenient rather than high fidelity.
