Vaprlife absolutely has the worst product and the worst customer service on top of it.
I have a whole bunch of mods from other suppliers, and there have been issues with product performance. However, these issues were all resolved promptly and courteously (notcigs and provape). S..t happens, especially in a new industry, but one can at least ask to be treated with some respect as a customer.
When I had issues with intermittent contact and rattling right out of the box with a Joker VV, Vaprlife's answer was "your atty is shorting", even though I had stated that the same attys (plural) worked fine on other VV PV's (Big Brother and Buzz). I politely resent the email. The answer "well, you must be doing something else wrong", of course with a lag time of up to a week before I got any answer whatsoever. Some $40 and a month later between restocking fee and postage, Vaprlife has a very bitter customer.
Of course, there will be sheep who will stand up for a bad supplier, regardless of how well one documents the issues. One always gets those who say "mine works fine; there must be something wrong with you".
For me, the Joker was a joke as well as Vaprlife's customer service. Apparently, there are a lot more than just one of me out there. In an industry where word of mouth is the main promotion method, the word on Vaprlife is not good.
