I’ve tried a few a few Tenga products with handy, thought I could share some experience…
Tenga 3D
My favorite Tenga product. Expected these to work but a bit underwhelming. When flipped over there’d be no texture for the band to latch onto. It must be strapped tight around the entrance. Thanks to that added pressure ZEN and SPIRAL hurts a little. POLYGON works, a very mild one, though.
Tenga Crysta
The thing is in a cuboid shape and has thick walls. You have to fully unwind your velcro to strap it on. It can be strapped at any position of the toy, not just bottom, which is very nice. Do not fasten it too tight otherwise it hurts - those orbs aren’t kidding. It’s tricky but once I get the gist it’s the most stimulating one I’ve used.
Tenga Flex
Really easy to be strapped in place thanks to its case. Not really a lot of vacuum as advertised - a good thing for using with the handy.
Enjoyed the white one, snuggy. Mild stimulation. The black variant is even tighter and its harder texture has brought me more pain than pleasure.
