After much adjustment on the leg straps, I found it to be comfortable. In the future, I would probably say wider leg straps would be more comfortable.
The height was good. I will probably make some adjustments. Just about every strap on the pouch is adjustable, so you can really make it adapt well. You can even remove one of the leg straps, if you want it higher on the thigh.
All told, it works well. Only disappointing thing is that when you remove one mag, the retention for the other mag is almost nil. If I was at a run, it would probably fly out. Of course, you could resecure the cover. The pouch itself felt very secure on my leg. The front pocket and cargo pocket on that side become non-functional, so be prepared. Mounting it higher may allow for use of the cargo pocket.
Even fit my mags with Magpuls installed, although it pushed the Magpuls down over the mags quite a bit. But I am happy. The side pouches will accomidate my Punch II OC Spray and a surefire light, and the covers are totally adjustable. Good luck, and hope this helps!
