I used this solo for the two days I've had it, and I can say that it is STURDY. The material it is made out of requires cleaning after each session. However, the reservoir at the end of the tunnel does an excellent job catching any ejaculate. (Please don't use this as a condom for so many reasons)

Compared to other toys like it that I've used, it is very stiff in fact. The curves inside bend up a little when I'm in there. Which is a big sensation but takes some getting used to and has caused pain afterward.

The initial insertion makes a loud farting noise which can be mitigated by squeezing the air out of it before use.

I do enjoy that I can see what's going on in there and that it isn't shaped like a realistic vulva. In the two holes along the top, you can even insert bullet vibes, and that does feel very nice. Not enough to push me over without other stimulation, but still very pleasant.

I would not recommend long-term use, unless of course, you're into it hurting, in which case, please try it sideways for like an hour for maximum ouch.

That said I'm going to keep using it for a while, just to test out its durability.

When I received this product, it had some weird marks on the side where it looked like it had molded to the inside of a bag. Not affecting its performance, but if you're interested in the cosmetics of this product, you may be concerned. I'm waiting to see if they straighten themselves out but it's been two days.

All in all, you're getting what you pay for, wish there was some softer stretchier material that was as translucent. I'll keep shopping, I suppose.
