I have tried the temperature control now, and it seems to be very consistent. I have not tried the custom curves yet. I don't know if there is a better mod for the price, perhaps there is, but I sure am enjoying this Cylon. The menus are easy to use once you get the hang of it.Way back when I was power, before TC was a thing I liked the version of Curve that was around then.
I toyed with it a bit on the Cylon and it's worth trying. I think I did like it a bit more than straight TC but didn't feel like messing around to figure out what I liked best.
Once I start building a heavier fused clapton for TC like I plan to take up the room in my TFV4 I probably will at least use curve to give it a warm up boost at the start.
My only complaint is that with the Star Trek wallpaper on it, I have still not been able to use it as a Communicator. Beam me up!
