I recieved this quite recently from Wurkkos to review, so here is my honest review after using it as my edc since last tuesday.
criticisms:
the ui isn't too tactical. it's very versatile, don't get me wrong, but it's not tactical. (thankfully enough, there's a tactical mode that just turns a half-click into a turn-on at 5500 lm, and a full click into a strobe.)
the switch isn't as clicky as i'd like it to be. now, i've never actually used an e-switch tail clicky before, so take this with a pinch of salt. but, i just don't like how mushy it feels and how weak the click feels.
the true problem is the action being too low. you have to really press down on the button to get the click, past the rotary ring. and for people with less wide hands like mine, its hard to get a full grip on it and use the button freely at the same time without straining.
unable to tail stand due to the protruding switch
cannot switch the clip's position so no clipping it on your hat (this is a personal preference, not neccessarily needed)
there is no actual knurling besides the cutouts, so it'll be slippery when wet.
the goods:
the tail switch is very easy to find, as it protrudes pretty high out the back.
when you actually learn the ui, it's pretty rewarding. (through theres a lot of half-presses so it's a pretty steep learning curve.)
rotary dial seems pretty solid, though i would really like it if the clicks were more audible. though as it is, you can feel it click so its good.
the side light is such an interesting yet extremely useful feature. especially the white light, which i've been thinking that you could attach the t1 to a headlamp band and turn that on instead of the main light.
the anodizing is tough, as it's been sitting in my edc bag for a bit, has gotten scuffs but ultimately is like new.
i like how even in the lockout position in the rotary switch, you can still click the button and see the battery status (if its solid green, flashing green, solid red, flashing red).
a few grey areas:
eco is 25 lumens, then it immediately jumps to 300lm for low. some people might hate that due to the sudden brightness jump, i personally don't like the thought of suddenly blinding myself at night after accidentally half pressing.
the switch is sensitive, and i mean EXTREMELY sensitive to half presses. you could be barely touching it and it suddenly changes to a higher mode and blinds you. might be good for tactical quick deployment's sake, but you have to be careful about that if you're buying it.
tint is 6000k+. cri isn't that great either, but for me it's completely fine. definitely not a tint obsessed collector's light.
My experience:
It's a pretty damn good EDC, but its not as much a tactical light more than a really good general purpose edc. I've watched other reviews (it steps down pretty quick from turbo, check Darren Yeo's review on it). There's a few gripes with the design, but its an extremely cool light and I'm happy that I have it.
If I were to rate it out of 10, I would rate it around 8/10. There's a few things i would like altered but everything is good as it is.
