Ok, I bought one.
First impression: Nice looking, good finish and trim;
Second impression: Clean, good threads, o-ring on head too small-won't seal, hmmmm;
Pop-in AW: turns on, three mode, medium and low are too bright, high 200+ lumens, clean beam;
Oh,Oh, What's this! One clip screw loose and stripped. Can go up in size-no sweat.
And, after just 15 mins, switch stops working. Sometimes yes, mostly no.
Try and trouble shoot, no go. Lego-in a Mcclicky without brass fitting ring. Ha! Works with a small strip of Cu tape to make circuit to unanodized threads,and remove stud inside rubber cap. It's snug, without movement. Hopefully finish of fix-up. Alas, get what you pay for!
Anyone else run in to fixable, or not, problems?
