So I've had it a few weeks, the button was always iffy and needed a firm press to fire out the box (I just assumed that was normal ) now its gone wonky, the wattage just scrolls all the way up to 70 by itself and won't fire, buttons don't work either, remove battery and it just starts again. I left overnight and it worked for a bit this morning but now doing it again, I've had no leaking just condensation but cleaned out frequently anyway. It was bought on Ft and this is what's worrying me as don't fancy sending back to China,, bit gutted as I love the mod
