Wismec RX Machina Mech Kit review | Why I prefer mech?

  As the smallest 18650/20700 mech mod, Wismec RX Machina truly worth the words, the whole size of the mech tube is 81.3mm * 28mm, it "moves all the functional button parts up into the 510 section and has the smallest possible profile for the 20700/18650" battery, as their website say.  Another place makes it special is the replaceable resin tube, as a mech fan, one color usually can not last long for love. So this design make sense and also make us to clean the tube very easily. After fully checking the Guillotine RDA and it's accessories, I realize it's not only can be used as a normal RDA but also features for BF squonk, another BF electronic pin in the accessory bag that you can replace. So how do you feel about it? Would you want to try? Wismec RX Machina kit $32.9
