Props before constructive criticism: these models are terrific. They move well, and they're quite pleasurable.
The problems are thus:
For the Peridise set, the plastic flanges that keep the toy from disappearing don't feel good. The plastic edge at the tip (the part that curls upward) is too pronounced, which detracts from the pleasure. It is irritating to keep having to adjust the toy manually to keep it from hurting. It's also too thin, which makes it press into the tissue too much along its top cradle line. It would be much better if it had a wider oval flange with rounded edges like the Tempo. Even just a bit of extra thickness, say, 2-3 times wider, would help. So would putting a small ball on the pointy ends, a little like a mini P/K tab, or flattening the points out.
The Tempo is superior to the Peridises but for one thing, and that's also the edge along the very bottom (the flat part). This too digs in uncomfortably at times, where the tissue goes around the very distinct edge. Just rounding the edges would help, something that would result from dremeling it, say.
Thanks much for the time.

The Tempo and the Peridise models are not intended to be completely inserted to the "flange". Properly inserted you should still be able to feel the last bead before the flange. Inserted this way, you should feel no discomfort.
