Thank you for the quick replies!
I assure you I understand the risks of scarring from DIY-electrolysis and I do not plan to do any facial work unless I become sufficiently skilled.
I wonder if I understand the functionality of some of the analog Clareblend models.
I guess the one you call Ultra Clareblend is this one: Clareblend UltraBlend
Yesterday a Clareblend Model #8301 was sold for $112.50.
There is also this one for sale on ebay now: Clareblend Model #8101
From the look of the pictures, 8101 seems to be the simplest with just one dial to set the galvanic current and one to set the thermolysis energy. The 8301 seems to be similar but with an added autoblend unit, which I assume somehow automatically match the thermolysis energy to the galvanic current so you only need to turn one dial. The Ultrablend looks more modern but it is hard for me to tell what extra features it has. It seems to be able to do flash thermolysis but I guess this is not something I will use until much later in my learning process. What other advantages does it offer compared to the older models?
Btw, is this
the Silhouet-Tone machine you are talking about? I am a bit curious about it too. Can anyone identify the model and say anything about it?
