Best inflatable Nozzle

I had one of the Cleanstream inflatables. The way it's constructed (ridges) makes me very sore if I do more than one insertion. My wife couldn't tolerate even the one...

So what's the best?

Suggestions welcome, and I see that SiiconeNozzles has an offering that looks pretty good, but it's fairly sizeable. I can take that, but not so sure about my girl. It looks like it's man size, and she's not.

Suggestions?

The latex one is much easier to handle, though it has a much smaller inner balloon aswell...

You can buy em anywhere online, medtech3000.de has em, but you need to know some german to order

Siliconenozzles has said that they will be expanding their line soon.

Would be nice if Klystra was brought back...

@moliere, that's the funnist, punniest, unintentional innuendo I've read in a while...
