It feels a little bit flimsy because the palm rest is only attached in a small area. Adding an extra connection between some of the feet on either side of that connection fixes that entirely. I’ve done it with a baseplate and that allows me to attach hem to tripods, clamps, etc. too.

They could definitely be more portable though. I’ve just picked us a mutch smaller Geist Totem to those ends. I’m hoping to build it over the holidays.

Have you considered a glove80?
