Review (5/5): Patience required, and rewarded, by good results.
Does exactly what it is supposed to do. A couple tips and tricks I've picked up along the way:
1) There is a continuity buzzer that will let you know that you have completed a good circuit (remember the saltwater on your fingers!)
--> The buzzer length is about 8 seconds and then repeats. You can use this to keep the probe in for the recommended 15 seconds (two long beeps)
2) The tweezers are just ok. A person with 120 grit sandpaper and a bit of patience can get the surfaces mating perfectly and give the tweezers a positive grip
3) There are two included probes, and the super-thin probe wires are reasonably stiff, but also brittle. I've broken one already trying to straighten the wire after I bent it.
4) The process is NOT instantaneous... after treatment the hair will still feel firmly attached. Give it an hour or two for the chemical reaction you created to break down the follicle.
5) The process will almost certainly only kill "many" of the hair producing cells in the follicle, but not "all". You will see regrowth, albeit much finer hairs, which should fade with additional treatments.
