I found the box of cables I had packed, and updated to the new firmware.
I've only used it for one session. I like the warmup concept, though I can't say I've used it enough to judge the result. Also, it may have been the first session in which it didn't either freeze up or jump out of Cruise.
I did find a few quirks though, which I'll list here;
1) I had my device set previously to change temperature in 5 degree increments. Initially, it seems it overwrote the setting and was changing in 1 degree increments. After changing back to 5, instead of reading 360, 365, 370, etc., it was 362, 367, 372.....not a big deal, but odd. Maybe I overlooked a setting, I dunno.
EDIT: Probably because of the set temp being 362 after changing in 1-degree increments, you dummy!
2) It displayed an incorrect Resustance value, though it did read correctly when I hit the fire button. Again, it doesn't seem to be a big deal. Besides, that occasionally happened with previous versions, though I think this was more extreme in terms of variance. As it did ultimately display the correct value, I'd rate this as insignificant.
3) I had the temperature set to about 375F and wasn't getting any vapor. I pulled the stem, as I thought it might need a stir, and discovered it was barely warm (I could press my finger to the tophat). I looked at the screen and discovered the set temperature had dropped to something like 175F (don't recall the exact number).
Keep in mind that I've only done one session with this firmware, but the last issue may be somewhat concerning; the end result would be the same as jumping out of cruise or freezing, as with any of the three errors no vapor can be produced.
I love my Tubo, but I'm looking forward to the Dual. In the meantime though, even with its quirks, I'll pick up the Tubo over any other portable at hand.
