I own the tenga spinner hexa(02), shell(03), pixel(04), beads(05), and brick(06, regular and soft editions). I use them all semi regularly in the handy and they are my go to over any of the handy sleeves simply because they feel better.
The problem with recommending any of these is that my preference and how good it feels can change week to week based on sensitivity. I started with the hexa and liked it because you can feel all the little features. I’m an average size in all dimensions so any of the middle of the road spinners are a nice middle ground of pleasure and intensity. Then I tried the pixel which was less intense, good for edging, but as I got less sensitive, I didn’t really feel anything because the pixel’s texture is fairly smooth compared to the others so I stopped using it.
My use case is long intense sessions with not a lot of sensitivity so the pixel or hexa might be ok for round 1, but it just doesn’t feel like much after that. That’s why my go to has always been the brick. At first, soft edition but then I used it to death so now regular edition. I found the regular brick to be too intense at first, but adding lots of lube helped and now it’s just perfect for me. It’s just intense enough to use on PMVs, Fap-Hero and keep going right on that mind-blowing edge for hours. Round 2, 3, 4 it matters not. If you’re soft or hard it matters not. It just works.
My other go to sleeve is beads. Beads has these larger spherical features that you can feel more on slower scripts, specifically oral scripts. It’s a pretty interesting feeling that I don’t really get with other sleeves and their smaller, more uniform textures. If you’re more on the sensitive side, I’d probably recommend beads for the edging, slower side of things. Then brick soft edition for the more intense side.
I don’t really have anything to say about the shell simply because it doesn’t really do anything for me. I don’t know why, but everytime I’ve tried, it doesn’t get me anywhere. No particular reason, just always have a mediocre experience with it. Doesn’t hit the right spots or something.
As for general advice on the spinners, I will say that they’ve lasted me well over a year with heavy usage. 50-100+ times on my favorite ones. They tend to fail all in the same way which is by their layers separating. The inner coil is contained by an inner and outer layer of material. These separate over time around the opening hole and the middle. It’s still generally usable, but it got so bad on the brick soft edition that I couldn’t use it anymore. I am fairly rough with mine though so your experience may differ.
Also recently printed off a clip on extender for the handy. Highly recommend. I find that for an optimal experience, the elastic band needs to be tightened right at the edge of the spinner’s opening. This keeps the opening nice and tight. The problem is that the handy’s stroke doesn’t go down quite far enough past the machine when the spinner is like this to bottom you out on a full stroke. Depending on your hands free setup, the machine tends to hit your balls if you try to mount it closer to go down farther. An unpleasant experience.
The Optimised_92.5mm_slider_extender_clip-on_with_belt_stops_and_easier_clip-on_main_strap_at_bottom.stl by abdulis is what I started using and it provides that horizontal clearance to get your junk out of the way and a little more vertical movement to bottom out.
All in all, highly recommend the tenga spinners for the handy, especially people who like it intense because they’re so light and small that you can use them with intense scripts for hours and not overheat the handy. They’re also inexpensive enough that you can try quite a few and see what works for you. Hope you find one you like and good luck!
