Where you can
contact them. Do not know if they'll sell the part on it's own. Figure contacting them would be the way to find out.
Find a lot of vaping gear manufactures do not offer the best customer services. Wofoto being as respectable as they seem to be in the industry might be the exception. Not ever dealt with them to know.
I usually buy a lot of *ahem* more frugally priced gear. A lot of the stuff I get is styled versions or clones. Not that I don't have some authentic gear, I do. More inclined though to buy from Fast Tech who clearly sells lower cost gear.
Fast Tech by the way has excellent customer service as far as I'm aware. Note though they are not manufactures themselves. They can and will offer replacements. Usually you need to post a picture of the faulty gear
if it arrived faulty. Don't cheat them, they will know.
Many folks here buy from Fast Tech. We are secretly hired as Chinese agents of customer services and fraud detection spies. *chuckles*
