I asked for my money back but the place I bought it at says its crafties responsibility and crafty says its the the merchants . A total circle jerk
I think the reason you were on a "circle jerk" is because you asked for your money back rather than a fix, a fix is covered under warranty while a refund is generally not, sounds like the retailer that you bought it from is giving you store credit? If so its good that you got a solution, maybe look at something like the arizer air/solo or a butane vape for something a little more rock solid with regards to reliability.
I'm sorry you have had so much trouble with your units, just for my own curiosity how many hours did each unit reach? And what was the reason for each return? (Was it housing cracking, button failure or lights of death) and any comments on your usage? I'm not looking for reasons to put any blame on you just to get a better picture.
And just to add a little balance, I bought my crafty in March and it's still running great (although this last week my Bluetooth seems not to work, but I have it set at 190°c/210°c which are the only temps I use it at now anyway) while I acknowledge this is not the 'norm' for everyone, it seems we are at opposite ends of the reliability scale while I think most fit somewhere in the middle.
