For men who wish to wear this extension, it's better suited for those in the 4-5" range. Longer than that and you will not receive any stimulation to the base of your shaft due to the base of the sleeve blocking deeper thrusts.

It seems as if a more appropriate use for this extension is for smaller vibes or dildos, as you would not lose any thrusting capability, but would instead enhance what could be seen as a weaker item.

The material on this sleeve is stretchy, but it is also firm. When tugging and pulling to test the stretchiness, there was some give, but not as much as with other extension sleeves. The rounded nubs are soft, while still being somewhat firm to offer more stimulation. The three little curved ticklers on the upper part of the sleeve are probably the most flexible part of the item, very soft to the touch and easy to bend or move.

Overall, the design is okay. It's not really fun for those who like longer shafts to penetrate them, due to the base cutting it short at a mere 4-5 inches. While it can enhance guys with smaller shafts, a man with anything over 7" is going to be losing out on the stimulation, though it still may be good for his partner.

It's easy to wear, and the tip is more realistic in shape to make for easier penetrations. There is no strap for the balls with this item, but it is somewhat snug to help keep its place during use.

As short as this one is, it seems like to get the most out of it, you need to stick it on a dildo or vibrator that you can twist and rotate while it's inside you. The thrusting length is smaller than average, so the feeling of the nubs rotating and stroking inside you can be a much more rewarding pleasure.
