If you can temper by hand then you do not need a tempering machine like the Rev 1. Normally you would use one this size if you did not know how to do it by hand or did not have a marble or other cooling slab.
Thank you soooo much! This is very helpful!
I have a Chocovision Rev. 1.
Does anyone else have one? I am learning how to use it, but I do not see its usefulness.
