This bumper is one of very few products I've found that will protect a Moto Z3 Play while still allowing use of the battery mod (haven't tried other mods).

It protects the phone and the Moto mods

With tempered glass and a decent Moto mod, it's ok at best.

Maybe Moto will wise up and upgrade the 5G mods with a notch to allow use with bumper covers.

First off, I own the Moto Z2Force CaseWe bumper case and loved it
