Bought this for the very reason it is marketed. It was a great "starter" Fleshlight for me, although I have had others long ago. Good if you want to put in the work without going over the edge too easily.

This is my second STUB I have lost my old STUB from one of my moves. Have always enjoyed edging with this. Entry is snug and texture is stimulating but easy to back off and hold da nut..

Tight AF My girl uses this to edge me. Incredible.

Better than Lady Get this over the Lady if you want even more intensity. Slightly harder to clean since the orifice opening is smaller than the Lady but it's worth it for the greater intensity.

Pretty good Well made product and quality material. I don't have a small member by any means, but I still hoped for a tighter fit. I would love a version that has almost no internal diameter (like a clenched butt) with a strong textured surface.
B. M. 4/5 Verified
Really does feel like the real thing. Helpful in getting you used to the feeling you should be expecting when having sex with a partner. Would benefit from clearer instructions about cleaning and maintenance.

Amazing but one small problem... I love the products I bought but the bonus Halloween quickshot case had a small plastic piece break and now I can�t reassemble the casing
G. H. 4/5 Verified
