Although I had issues with this toy both in use and with some issues with the product quality. I would still recommend this toy to my guy friends, or even my male partners for some really intense orgasms. The tightness is great, although it might be too tight for guys who are above average in cock size.

Grip-n-Stroke Too Tight for Comfort
The Grip-N-Stroke stays true to its name of GRIP, as this ribbed masturbator is definitely a tight fit for most males. It is not very easy to use to masturbate and stroke at a fast pace, as it is tight and secure. I believe the price of this product makes it worth trying to introduce yourself or a partner to masturbators, but I believe there are better or larger ones that will provide more satisfaction.
