The Silhouet-tone VMC is a fabulous epilator, on par with the Apilus SX- 500. I was grimacing as I was reading your post, Seana, because I have found life with a VMC to be extraordinarily easy to use, after I understood how it was meant to be used. 
I used the VMC for four years and still own it, although I have passed onward to an Apilus Platinum now. I can tell you through experience that I had no negativity associated with using this epilator! It was a dream machine.
I’m pretty sure you can do single needle galvanic by disabling the thermolysis side, but I may be mixing that up with the Gentronics digital I owned before the VMC! Most epilators allows one to do galvanic if there is a blend option and I would have to look at my VMC face plate again to know for sure.
I was never kicked out of a program. Don’t understand that part? If you go to a preset, there is a modulation key that allows you to adjust up or down to +50 to
-50. The modulation key is that larger black button in the middle.
[b]If the automatic sensor didn’t work on the VMC, but the footswitch did, that signifies that the needle holder or the indifferent electrode cord needs to be replaced. [/b]
Let me emphasize for the hundredth time on this bulletin board, that the presets are helpful and the operator DOES have complete and precise control of the epilator, more so than with a knob job, if they know what the heck they are doing! You can expand or contract from the preset if you have to. You have to learn the language and grammar of the particular epilator brand you are using. There are hundreds of combinations of possible settings and you learn those combinations as you log in hours and hours on the epilator. The more you use it, the smarter you get.
Frankly, most schools I have heard about and the school I attended had several brand epilators, old and new, to sample and even the top dog of the school ( the instructor or someone above her) didn’t know how to use them!! We were told to get the instruction book and learn on our own. Maybe that is why I have made it my personal hobby to try and test drive any epilator that I can get for a hands on experience.
Epilators with presets are awesome because they give you a place to start. Those presets are not random selections. Beta testing was done on human subjects to help determine the best combinations. Basic epilators that don’t have presets work much the same way. The manufacturer provides a guide, like a timing and intensity chart for fine, medium, coarse and very coarse hairs. If you go to a high timing and a high intensity, you will be kicked out of the program on some brands by a frantic ding warning on other brands telling you not to go there!. It is a safety feature that screams, “Dummy! You can’t do that!” .
Not understanding how the epilator works is the fault of the thinking person sitting next to it. The VMC, with its presets, can be adjusted to one’s desires and needs. It is a high tech, quality epilator that just needs to be understood better. Sensation-wise, it is very, very comfortable, right up there with the Instantron, the Platinum models, SX-500, Senior II. The VMC hits you with a small diversion current and then it sneaks in the big current right underneath the little pulses, unlike the Apilus SX-500 that has an arc of warming. It has a slowly increasing energy level inside that arc.
There are several good epilators, with great presets . All it takes is a little time to learn the best settings and how to gradually adjust those presets, if they need any adjusting at all, so you can make your own custom settings for your clients.
I worked an hour on a woman’s upper lip tonight starting in a preset on the Apilus Platinum. Within that hour, I adjusted up and I adjusted down more than a few times, to suit the hair structure and area of the lip being treated. Yesterday, I removed hairs on knuckles , an ouchy area indeed, with Instantron’s Elite Spectrum. No presets on the Spectrum, but I was able to work within the parameters suggested by the manufacturer for fine hair structures and tweaked the intensity up and down as needed. By the way, the Spectrum is an easy to understand and very comfortable epilator! You take it out of the box, look at it for a few minutes and you know instantly what to do if you are a professional electrologist. Very nice epilator that offers blend as well. Will have to check if you can do single needle galvanic only? Oh, well…
Time to watch Jay Leno!
