It looks like an ok unit. Certainly beefier than a One Touch and the settings and LEDs will certainly facilitate the process. A little pricey for what it is, but it should last longer than a One Touch and using professional needles is less frustrating than using those provided with the One Touch.
The things that concerns me the most is that it Automatically starts the current when the needle comes in contact with your skin. If you are working on a follicle thats difficult to determine the angle/depth/location, then you will be burning the skin surface as you probe. If you purchase this unit, I would suggest adding a foot activated switch between the “Return lead” and the front panel, which would be easy to do. Then this unit should work just fine.
