For those interested, picked myself up a couple of these to secure my RP Trx on my on-camera PWII for remote control of some speedlights while using PWIIs to trigger strobes and some other Rube Goldberg projects. These are the units Profoto sells as optional to secure their Air Transceiver to the back of your meter, etc.

Nice solid grasp of my PW and RP hotshoe. Seems sticky enough, but while can't speak to the long-term 'tooth' of the adhesive, as you can see they come equipped with two slots for zipties, etc for a mechanical attachment.

Might come in handy for some folks.
