I use the base of a Vargo Triad XE Ti stove B/C I can fit 2 ESBIT or FireLite tabs in when I want a faster boil. My BPL Ti folding stove holds only one tab so that's my survival kit stove.
But I do use my Triad EX base a lot lately and its other good feature is that I can blow out unused tabs & re-use them the next meal. I just put the Triad XE & left-over tabs still stuck to it into a small ziploc sandwich bag to keep my "cook bag" kit clean.
If an ESBIT stove can't hold partially burned tabs when stored it's a PITA.
