I switch between a KFL+v2 and a veritas (both authentic) as toppers. Ive only run flat tops in mine, because the switch is barely recessed. If I used a button top, it would make the switch stick out.Ok....time for what is possibly a stupid question (but you know what they say). I have, and have had, quite a few mech mods. But none with direct atomizer/battery contact like the 4Nine and SMPL among others. The SMPL really appeals to me but I am curious about several things. Will it work with button as well as flat top batteries? I have read this is for experienced users only as you may get a short in the battery.Please explain, because I am kind of denseI love the plain look and that it is Made in USA, just curious about any drawbacks, disadvantages, etc. So please educate me. If this has been addressed and thoroughly explained elsewhere I do apologize. A very Happy Thanksgiving to all and may you spend it with friends and family.
