Wow! That is so worrying. I use eight Cleitos and vape a lot (use other tanks too). Must have been through 40 or 50 coils (as I buy everything by PayPal I could check that and may do one day).
Only ever 2 maybe 3 coil problems, one shorted and the other one or maybe two were short lived though that could have been my fault can't recall but I don't have any problems with leaks or spitting.
I do read quite a few people have issues though so maybe I've been very lucky or it could be where I've bought from.
This business of changes in Aspire distributors may be part of all this?
It's a real shame because as you say for stock coils when they work they're excellent.
Just counted, been using six Cleitos today, currently using five, all behaving perfectly well on three different mod types.
