full disclosure i have trichotillomania and do generally get a little bit of physical enjoyment from pain so [SEP] when i initially read reviews for this i was excited to see people complaining about it being tedious and painful that is honestly what i was kind of hoping for guys let us be real getting this done professionally is also tedious and painful but you are on someone elses schedule i am so here for the convenience of just being able to sit down and do this tedious painful task on my own time while watching season after season of always sunny in philadelphia a few things i learned using salt water rather than just regular water is crucial you cannot do this to someone else it do not work it means personal when it says personal i am going to guess it has something to do with science electrical current but i do not actually know i just found that i could not help my sister out with the little black hairs on her neck but when she held the wand herself it worked fine yes that is lye yes those are burns aquaphorit is performing the job it is meant to do which is a painful tedious job but it absolutely does what it says it will do the only reason i am not giving it five stars for fulfilling it is intended purpose as described is because of that annoying beeping i do not understand the purpose of that it is irritating why not use a pleasant led light fade on the box instead something that does not scream at me maybethere had to have been other design options
