My “pink” Ti has brass showing in the gap between the head and body about 1/16 - not ano. like in the pictures. It makes a nice accent but seems a little unfinished. I wonder how long that piece of sponge rubber that it uses for a spring lasts? It looks hard to replace.
There’s no problem with o-ring seal. It’s deep. You’ll only get rid of the brass ring reveal if you remove the battery. It ain’t broke so don’t worry about fixin’ it.
I had thought about the sponge material myself. If it flattens with wear, surely there must be a replacement. Dunno.
Maybe ask em.
ETA: Above said, I actually made one for the P0 with flex tubing. Then 4 sevens came out with a redesign of a resilient long lasting type of rubber one. So it’s doable even if Thrunite doesn’t offer a replacement.
BACK ON TOPIC….MINE WAS A BLACK FIREFLY
Got a blue, 3 lm Ti, very happy with it.
Rather loose head. Changed the o-ring with a slightly thicker one to prevent accidental turn-on or that it looses its head while mingling with my keys.
Mines a 3 lumen gold and … bent. Oh well so much for that. 
Bent?
+1
Got a gold 3 lumen low. Not exactly the color and low mode I was looking forward to, but for $5 I can’t complain.
Got mine today green with 3 lumen firefly mode…
The brass pill was pressed into the head at a slight angle so it didn’t go all the way in. It was sort of crooked/bent when you screwed the pill head assembly on the body. I was able to press it in fully via hammer and cutting board and it corrected itself.
Happy now with that.
So far Red is <33% and Gold is NOW the new black?
PS - I’ve been wondering what those who have the firefly had it say on the box. Mine says firefly and then 3 lumens so it’s not really a firefly. On the T10’s true firefly I can look direct at the emitter and not squint . . can’t do that on the Ti 3 lumen version.
You're right the firefly is much dimmer than the 3 lumen version ..I got a gold 3 lumen and wish I got the pink/red instead .
The 3 lumens is an excellent low ..
Black with firefly mode. Exactly the one I was hoping for and a steal for five bucks. Very happy!
Gold/3 lumin here.
Mine is more gold and less orange than in the pic.
Gold 3 lumen variant for me.
I sold mine already, as I was really only interested in the Firefly. I had actually intended to mod mine so that it was a single mode 0.04 lumen light, but it wasn’t in the cards.
Meh, I got the gold/orange 3 lumen version. I was order number 38 and at that time the deal looked like it was going to be a black firefly version. Kinda bummed about that.
Still a good deal for 5 bucks though.
I got a black firefly .
I approve of this .
I hope that was a joke. Why on earth would you want to mod it to be low power only? Just buy a crappy $2 light from the hardware store and you have a dim light that is not good for much. I bought a AAA single mode from DD for $1.80 shipped, it is prob 1 lumin and has a clicky.
Still can’t answer the poll. I got a registered mail slip yesterday. Went to the post office to get it this morning and there was too long a line to stand in for a $5 light (plus I was already late for work). They’re not open Saturday and they never try to re-deliver registered mail, so looks like Monday. I like tracking, but registered mail just delays things for me.
Gold 3 lumen here.
Was informed by my sweetie that I have a package in the mail. It should be the Ti and I’m praying I don’t find a gold 3-lumen jobber. I really want firefly mode in just about any color but gold. Will update when I get home and unwrap it. 
Update: no Ti, just a pair of 14500 IMR cells. Maybe tomorrow.
