I just got the
ipv 4 100w. In the manual it says it can be upgraded to Temp Control online. I kind of have my doubts about that, but that is what the manual says in the box with mine. I will say it is not small, but I have a SXmini and a Flask. The
ipv 4 is taller than the Flask, but not as wide. It fits and feels great in the hand. I do have kind of large hands, (long fingers) so that may be why it feels very natural to me.
I am going to download the upgrade (TC) and will let you know if it actually works on the version I just received today.
From manual: "The temp control function can be carried after the upgrade progress"
