It's so funny, since receiving my lube from Pax last week, I have not had the temp light issue once, not one damn time, and I use my Pax daily.
I'm just going to keep using it until I need the lube.
I'm not questioning the earlier poster who advised not to buy a Pax based on his experience, but his experience has not at all been mine. Have I experienced the temp light issue? Yes, although once I fine-tuned my cleaning methods, it has not been a problem at all. I "deep clean" my Pax about every 3-4 sessions, and I just don't have many issues anymore. I am wondering if that guy has the original mouthpiece.
My advice to someone who is interested in a Pax: Know what you are buying. This device CAN be a little finicky, but it is easily manageable if you take care of it, and the care is not as involved as many make it out to be. Plus, Ploom's customer service is proven quality, and they give a 10-year warranty. It's a no-brainer to me, and I have not once regretted buying my Pax. Yes, the battery does diminish over time, but show me a battery vape that doesn't. If you want a vape that you can misuse and neglect, this one is not the one for you, but don't be scared of the rumors either. This is an excellent vape.
