Maybe, maybe not.
First thing you'd have to do is ascertain whether it's actually the switch that has failed - and it would also have to be shown that there's never been any fluid ingress (water, juice, whatever).
Then, you'd have to find the specs from the switch manufacturer - and assume you're within that figure.
Then, you'd have to show that the mod manufacturer had knowingly selected an inappropriate switch - as in that the manufacturer knew the average vaper is likely to hit that button more.
So, say you got documentation to show that vaporesso considered 100,000 clicks per year to be average and they still specifically chose a 50k switch.
After all that, you might have a case.
But then a perfectly valid defence would be "we aim this product at the mid-premium market, where most users would have this as a second or even third device showing commensurately lower use with greater care".
I know it's annoying, but I honestly think you're into a loser with this.
I've bought all my vape stuff (including the battery charger) on the premise it's a 6 month device - a failure within that time and it gets sorted one way or another - any life past 6 months is a bonus because trying to get a fix done after that just isn't worth the hassle.
In all honesty, the revenger is like 60 quid for the kit - that's nowhere near a premium price tag.
As a 6 month device, it's a tenner a month - and you've had 4 extra months as a bonus.
