That would be because 99.9% of Chinese devices are so poorly manufactured and fail at a very high rate.... Most recently the Kui and Geyscano are prime examples of this. I have purchased more than my fair share of Chinese devices in my 3 1/2 yr journey so far and haven't seen a quality Chinese device yet!!! This is basically why I choose to now, spend my money on things that have a proven track record, are of high quality, and are backed by honest customer service...Folks around here often tend to bad mouth clones and Chinese made mods without having seen one in person.
That basically implies to new vapers that some experienced vapers are biased in their opinions.
New vapers rely on experienced vapers for product information.
Some of us "experienced" vapers aren't biased in our opinions as some might think and are only passing on information based on the mistakes we made along way so far... This is why we sometimes are concerned when new vapers are so eager to throw away their money on worthless Chinese copies or clones that in no way shape or form can even come close to being compared to the original!!! We try to pass on some of our experience but are usually met with someone like you that is quick to play the fanboy card and then derail the thread for your own amusement, it seems.....
