This was my 1st toy and I have many now, but this continues to be one of my favorites as it is so easy to use and clean up, plus it gets me off. My lady enjoys it also, with either one of us using it to stroke me off.

Senso sapphire sex toy review
Overall it is an okay masturbator. If it was bigger and maybe the end was closed to allow for better suction and perhaps came with a lube pump, it would be a lot better.
