Just got my Caldera Esbit system, and my first impressions are so,so?
1) Seems as if the boil times are slower than my BPL Ti wing stove and Firelite 550 mug. (16oz water)
2) Actual overall tablet burn time seems much faster as well, with the Caldera system?
3) I have a hard time lifing the Fosters can out, without burning my hand, (yes this is with the beer band in place)
4) Stuff-sack fits too tight over the Fosters can/pot.
I'd like it to be large enough, to fit over the can, with a can cozy over the can as well, which would also protect the can while stuffed inside your pack.
With my BPL Ti wing stove I can boil 12-16oz of cold water, and still have enough Esbit left burning to heat another 12oz for my morning coffee (not to a boil, pre-treated water)
IMHO, there is way too much air space in the Cone, thus wasting heat or the transfer of heat.
What I've found with my BPL Ti wing stove, is that the tighter I wrap my windscreen around my pot the faster Boil times I get and the longer the tabs will burn.
I probably need to actually use the Caldera system longer though, before I pass final judgement.
