The replacement they sent me wasn't much better then then one I sent for warranty, so I sent mine back and got a new Solo 2. But I've been trying to tell people that some of these units run VERY hot! And this problem won't get fixed unless people complain. This is the same carp I went through with Boundless over their Tera. I'm not a skeptic, I've had terrible experience across they vape market with defective products, Storz & Bickel, Boundless, and Pax. And none of these except Boundless, ever admitted they had production issues! So Sadly, I don't expect any better from Arizer, based on my experience and what I'm hearing here. I know it's a hassle to do a warranty request but if people just put up with this, it will never get fixed. And it may shorten the life span of the vape.
