This was my first ever insertable estim toy. I got it based on the reviews and a few searches online. It is VERY well made and easy to disassemble for cleaning. I am pretty new to the estim world and I used this with my TENS unit. It worked fairly well but I did have to move it around a bit to get the proper feel. Still, it was lacking. I bought an ElectroPebble control box and tried it out tonight. Mother Of God!!! It was absolutely incredible! I am very happy with it and look forward to many years of fun with it.
