HI FC, Submitting this one humbly, VB2.5 is a continuation of VB2 yet it's a very different beast. What it can do: Heats up in 30 seconds (Room temp to 850F) Any temperature possible - Temp control is continuously variable Color feedback for at temp Robust heater, 1/4 inch thick silicone nitride Currently at $1199. Built in micro batches. (Inquire) Will have a bezel on the front as soon as it's done. If not we will send you a separate temperature gage to help you know the positions. How it's different: Auto-off is 10 minutes. The internals do not handle the heater being on forever like VB2. But it starts up in 30 sec so almost doesn't matter anymore. Pulls 650W+ at startup (VB2 is 150Wmax) note: both VB2 and VB2.5 are 40W continuous Dished out heater surface holds a puddle. Top temperature is only 850F, not as hot as VB2 (950-1000F), although the silicon nitride conducts heat quicker. Self cleans solid residue in 1-2 cycles. Ceramic heater surface has been said to create a finer aerosol with less spattering It's like we shrunk an enail controller into the housing, except with no display (that would melt) Silicon nitride (Si3N4) is meant to handle being red hot seconds after cold. It is such a hard substance it took us 2 days of working with a diamond saw to cut a corner off.

Both had sent their VB2s back for repair multiple times. I love the feedback they sent me! It was like new words were being invented. They are welcome to put their experiences here.
