So for the experienced users with 4810, I learned that you switch off the heat after 10-15 min., but do you still keep the cap and tip on?
I usually fill mine with warm, but not hot water, and don't use the heater, as I find the USC energy tends to keep the water warm. I just get it warm enough so the VG will thin out, then I shake it a LOT.

I've been using a little UC that my wife had,and it works,but is extreemly small,and no heat. It does generate some heat in the water though,if I use the cover while running it. How many 30 ml bottles do you think it will hold at one time?
I sure hope the one I ordered will work ok?
