I think that person's warranty had actually elapsed the way I read it? If we're talking about the same post!
My experience was exactly what I posted, I think
@tdriver had the exact same 4 years or more this way he said.
I sold my second unit after the period with some cosmetic cracking.
My RMA I paid shipping but they started sending shipping labels where I am since.
At around 23 months I used a jewellers loupe to inspect for cracking in good light or outdoor sun and found some.
It will be great if they crack! the formula with their newest vapes or switch to something else, but the service life I got was good value.
I used to spend 100 bucks a year on papers and thousands on tobacco before that, no more real need to visit 24 hour shops now either for same!
I had some alright ideas for a frame or shell to make a Mighty work good without the casing,
if I thought it would be a huge seller I might have got into making a few! But I think the demand for it would be hard to judge as time goes on.
Less chance now because I've sold it. Still not sure what vape to get with the money if anything, maybe another new Mighty sometime or if a plus comes!?
Crafty+ is doin fine for me meanwhile, we might get a suprise from some maker somewhere!
Never got the white marks much but I'd keep iso to a minimum. I used it up there occasionally, but mine cracked a but in the end too!
Selling and re-buying is always an option, although I am thinking private selling is possibly not going to be guaranteed 100% safe all the time either?!
So take care, but you should be fine!
EDIT - This person did well!:
Had the same issue with my first Mighty after about 2,5 years. Got an updated 2019 modell for 60 Euros as a return unit back then.
Located in Germany apparently, maybe that helps!
