Awesome solution to a problem we shouldn't have, MicroHDMI Sucks, but this makes it usable.
Well made, well thought-out product. For $10 it I'll save an expensive mainboard repair on a product. It's taken-out 2 HDMI cable-ends so far thanks to an errant boot, so this smallrig product is certainly sturdy!

Saves your micro-HDMI connector!
I have an older G85 in a quasi-rig, and one point of failure that I was always concerned with was the on-camera micro HDMI port. This solves that problem for me in a sense that I can stop the wear and tear of connecting & disconnecting the very fragile on-camera HDMI port. Not to mention this provides "cord weight" relief from the on-camera port as well. Highly recommend for anyone using an older Lumix G7 or G85 in a rig.

Does what it says on the box!
Bought this to alleviate the risks of bending/damaging the microHDMI port on my Sony ZV-1 if I want to plug it to an external monitor or a USB capture card. Basically screws the adapter you'd be carrying anyway and you screw it on your cage. Make sure to check your cage and where you intend to screw it (there's pretty much only one location on mine) as the cable is very short. You don't want to force it in the ZV1 either (kinda defeats the purpose). Recommended!
