Anybody has experience with Ventz?

Ventz - Rider Cooling System - Home

Looks like a good idea, here is some testing:

and a review:

2 problems are:
1. They don't work with Gauntlet style gloves (the only kind of gloves I would wear = deal breaker)
2. Your Jacket needs to have a loose fit in the sleeves...which means you need an ill-fitting jacket

These are huge limiting factors - both my jackets have tight sleeves - no way i'd be fitting these in even if i tried.

I saw these and thought about it while riding a few weeks ago. What I noticed (and maybe its because I come from a dirt bike background) is I keep my elbows bent almost at 3 and 10. Slightly higher sometimes. That plus how my jacket gets tight in the elbows would block whatever air flow id get from these. My forearms would get some wind though.
