I was looking at getting a NANO bottle for my sniper kit, looks like it would work well. I can fill it at the fire station myself, I am a volunteer fireman, seems like it would work better than a bottle warmer. Anyone had any luck with them?

Something i've considered but not got round to buying one , two things spring to mind , no bottle blanket/flat batteries & more important consistant runs to be had , win , win , win

I was thinking of using one to keep the pressure in the bottle, if it makes it run better that would just be a bonus to me, I dont have a bottle warmer now and its a pain taking it in and out to warm up.
