Harrells Precision rings anyone .?

Has anyone used any of the Harrells Precision ring offerings .? I like the fact they have dedicated 11mm & 3/8 sets w/ 60 degree dovetail angle & also a flip side version for either or.
Ive seen a pic of a tm1000 with them but can't find it.

I have used them and they were fine. I got them because they were what I could find in the right size.

What did you mount them on.?
I have a pair of the double screw on the way. I sure learned wayyyy more then I wanted to about dovetails today from Kelbly, Herrells & a whole slew of others.
. I just want perfect angle fit. I'm OCD like that on dovetails. Hopefully they fit.
