Streamlight Polytac Review

I bought my Polytac primarily because it was cheap a while back and I've been using if for a couple years now; here's a quick summary of my findings thus far.

Pros:
-Cost.  The light can be had for under $35 shipped.
-Uses relatively common CR123 batteries.
-Fits in common 1'' mounts.
-It works.   So far I all the Polytacs I own have kept on ticking even with use on rifles and shotguns.
-130 C4 LED output.   It's a nice white light with a good peripheral cone.
-Has o rings to seal out water on both the tail cap and lens cap.
-Lightweight.   Weighs 4.1oz with batteries.
-Comes in black, coyote, and bright yellow.

Cons:
-1 of the 3 I lights I have flickers slightly under recoil (can be seen at the beginning of the video).   Is it a huge issue for SD/HD?  Maybe.  I really doubt I'd ever shoot in the dark with the light off in a HD/SD situation but for use with night vision devices it's a different story.
-It's not as bright as some lights on the market.
