The Fit is so easy to rewick, and soak the coil in alcahol. The drinkable kind lol. The Fix is easier to pop off to get the deck out. Even though the Fix charges only at .5 mah, it saves the bucks and still doesn't take too long to charge. Very hard to rewick the infinix. The metal housing is very hard to get off and not break the other components. So for you rebuildable guys and gals, go for the fit. I love to vape. I love our nation, and might run for office soon lmao.
