I have one I used briefly with the IMR-9 lamp and a nailbender high-CRI drop-in. Very solid host, and very well thought out placement of the grip rings, as mentioned above. I very much appreciate the inclusion of smooth and crenelated steel bezel rings, as well as clicky and momentary tailcaps- I did use the tactical tailcap due to the high draw of the IMR-9 lamp, and had no problems with it. I'm not a huge fan of the color and styling, but that's merely personal preference, and the performance of the seraph 9 far outweighs the cosmetic issues. I am selling mine off only because I've decided to go with the e-series over p60 based lights-- otherwise, the seraph was the best "out fo the box" of all the p60 hosts I had.
