Highlighted the above to show the extreme, I know you know a lot, but you actually don't have experience here with Solo3 and are speaking a subjective opinion as universal truth... Because I don't think it is very tame as higher temps were near unbearable to me, which is rather typical for me with hybrid conduction (yes S3 is a hybrid and can lean one way or the other depending on the user), while I find the experience smoother with pure convection possibly even in direct comparison temp wise, though plain short stem direct path at high temp is typically not enjoyable with anything including more pure conduction, but hybrids can be the harshest this way imo (they really smack when they have the power so worthwhile especially the lower temps for me or with more cooling or water in pathway) Always value your opinion, just trying to help put it in some perspective
Actually forgot to mention, the first time I used it, loaded up the regular stem full, in on demand mode, intended to do the lowest setting, but did not realize it was on the middle 392 setting (tried it before reading the manual at all and did not understand much apparently lol) so my first hit with the stock 15 second timer I think was so intense, I did end up puffing on it for many smaller hits until it finally cleared the heat and stopped producing vapor (this had also overcooked the tip of course) so yeah definitely totally normal I'd say again!
