Black Collection - Medium

Perfectly sized. Nice and massive. The satin finish is not as effective for me as a polished device. I should have gotten the Bobble. Still it is wonderful.
ADMIN: Thank you for your comments, although there should be no difference in sensation whether the electrode is polished or satin, and if you had purchased the Bobble you may have been disappointed by the size as the Bobble is noticeably smaller than the Black Collection Medium.
