HC3R mags for 10/22....who's used them?

[I Lean]

I came across these mentioned on another website. Checking more into them, I see only positive reviews. I like the concept, and ordered a couple to try out. Does anyone have any experience with them, now that it's too late for me?

Saw it on Facebook a while back, they look great, my biggest gripe about my current 10/22 magazines are loading them. These look like they would be a lot easier.
