This may be a little tangential but I have an IPV8 and it is a very nice solid device. I saw a request for comparisons. Stack ranking the mods I have, Yihi SX series is on top. IPV8 is next. Then a couple of Smoks. After Smok a Vaperesso. I also have a couple of Wismecs and Eleafs which are pretty much bottom feeders, although I will always love the look of the little Eleaf pico, my first mod.
