@jsixtysix says (earlier in this thread) that he has scorched his ultem section. You can get spares though.Just picked up my Le Zephyr -- my current vape arsenal are all mechs and I plan to use this with my Jumbo Jet, thought it'd pair up nicely.
A bit hesitant about how the ULTEM will hold up against my mod -- heard at the shop that this is an atty best used on regulated mods because the ULTEM can melt and if it does, well there goes £120. Also. saw that Leo is selling spare ULTEM chambers on the site -- so seems like melting could definitely be a possibility...
Are any of you using it on an unregulated mod or heard of the melting?
There is no difference between using regulated or unregulated. If you have built your coil properly, and your coil is not touching the ultem, then it won't melt.
