Got my Glarestomper - really quick delivery, too. I have a Nexus 4 and I bought a gel-type bumper case from Amazon for £3 to use with the Glarestomper. I snipped up the velcro strap and stuck it to the edges of the bumper case avoiding power switch, etc.
It works perfectly, holds its shape nicely, phone+bumper+Glarestomper fits in the Tx clip without issue. Really neat solution. Best of all when I'm finished the Glarestomper and bumper can go into the flight case flat, so they fit under the foam in the lid, for example, taking up virtually no room.
Recommended. Thanks for letting me know about this one.
