my don came in the mail today , i love it works great and just feels right in the hand . will only imr 18350's work in mini mode . i have one 800 mah imr 18350 that works great but the other 1200 mah blue ultra fires that i purchased from madvapes awhile back are too long even with the adjustment screw backed out all the way . are all the protected 18350's too long for the don ?
