Ha! Just got that email. My purple (fastest) mk4 seems instant to me, I can't imagine I'd see a difference in performance to the "1 second" Thermapen One. I would notice the lightening of my wallet by $105 + shipping.
How many here are going for it?
I'm going to hold out for the Thermapen OneQuarter.
I’m in the same boat. When mine eventually craps out I’ll upgrade to this new one, but I can’t justify it right now. The model right now is close enough to instant for me.
Not buying another instant read thermometer until it can read the the temp in 1 picosecond, which we all know is the time it takes light in a vacuum to travel approximately 0.30 mm.
