«  Not to Buy »

For how long have you been using it? 8 months, but HS for 3 months .. I opened it to see why some pads were not working .. without the pads everything works beautifully, but when placed, it works one out of two times

Did you try many other models before getting this one? no, but I think I should have..

What is your opinion about the value for the price? very bad

Knowing what you know now, would you make the same choice? absolutely not ...
