The Catalyst Cyberskin Penis Extension

I think I have an average-sized penis, so this fits like a glove and the silicone material that it's made from is soo comfortable to wear. It's designed to cover the tip of the penis, so it easily stretches over the top of the glans.
The Cyberskin penis has solid glans, which provide the extension.
It adds about another inch to a penis, plus a bit more girth.
I have tried wearing it whilst flaccid also with an erection, and it is equally comfortable and easy to fit.
I have also tested it over my foreskin and with the foreskin rolled back - it's a good fit either way, but it might be more secure with the foreskin retracted.
I haven't tried it for intercourse yet, but I would avoid using a lubricant on your penis because I'm pretty certain the extender would slip off. Others are suggesting wearing a condom to keep the extender in place. Very happy with this purchase and with the service from Bondara.

This is our favourite sleeve so far. Fits well, stays on. I'd recommend using a condom with it for added reassurance. I just wish there were more size options for it. An extra inch either side would be perfect. Oh yes, this thing discoloured very quickly but for the price, just replace often.

This item is great. Slips nicely over flaccid penis to add an inch and a bit of girth. Bulks out swimwear and underwear when it matters. Shapes great but shame they don't make them more flesh coloured

It's rare to find a penis extension that fits so well. You can even put it on before you get hard and it absolutely won't come off. It's thin enough that it doesn't affect your feeling inside. I wish it was just 2-3 cm longer but it does give you a welcome extra inch.
