As I mentioned "Having owned their kit (and read many reviews), " I spent many hours on the phone with their reps, most of whom agreed. They’re just too bulky. Nearly all of them used their regular style holsters, not their transformers version.
If one lives in a place where they can wear bulky clothing, that probably helps. I do not.
For me, the other thing is if you carry multiple units over time, you have to keep swapping the bases. With my Kydex, I just grab and go. Much simpler.
