I just spent way too much effort boring out the c-zy 55 adapter piece to allow it to fit a cr-2 battery BY HAND ...
>>>Don't try this at home kids ..
I got it real close and got disgusted and ripped the label off the battery and replaced it with cellophane tape .
I have a new respect for battery tube construction .. or using the right tool for the right job ..what a pain ..
The fun began by putting a nitecore clip thru the little holes in the tail and getting one side attached to see what it would look like with a nitecore clip ..and reading up on drilling stainless steel.
My opinion is it needs to have an acid etched clip to darken it and give it a cool look .. stainless on stainless looks kind of dull . drilling 2 new holes in the tailcap could be done with a drill press ..
Operation easy - Has mode memory so starts where you want it .
Long travel - No - average I would say
Noisy ? - very subjective - but it does make noise - its not stealthy
Stuck - pressing it to activate - if you press from the edge of the button it can lock up - unlocks when you let go - cure is simple - dont click from the edge of the button , try to keep central pressure - and no problems
I have two of them the b9 and the b2s ..I described the clicky to old4570 as skrunchy ..meaning they make a weird sound or feel like the outside edges of the clicky are dragging down the side of something .It's not audible but it's a feeling like crunching a plastic bottle or chewing on packing foam peanuts.It works fine it's not something that bothers me .. this light is one of the best lights you'll ever buy .. dollar for dollar it's a winner .I have hundreds of lights and this one is in my top 5. I'm buying a second one with a neutral emitter ,I have a farka and appreciate the xeno brand too .reasons to buy this light? .. for one reason it's SS. It looks like a stainless steel nitecore D-10 .To me the xeno is oddly shaped and all the colors are ugly except black :P. Runtime on this light is great , driver is super efficient , it's screaming bright on a 14500 , the tint for being just a regular r5 is wonderful ..it's a beautiful light that I've been telling people to buy since the day I recieved it.Overall it's a very nice light.
