The rotating function was very good and after trying this machine you don't want another machine that only goes "up and down".
If I have to complain about something, it's a couple of things:
1. The loose vagina inside the machine is not very tight, it should be made smaller and tighter.
2. If you have a larger penis, the machine will "chop" if you push it too deep into the machine. This should be remedied.
I know they say the machine should have heat. This had it a little bit but only the first use. I usually boil the loose vagina in a kettle so it is very hot and the result is great!
Things that I think could be done and improved with a future model:
1. Make the vagina "suctionable", with a button you can increase or decrease the suction and tightness.
2. Heat, a button that regulates high heat or lower. Also kasnke a button for vibrations and shakes.
3. The spin function has 3 different modes. It spins and pauses. I would have liked it to have been made so that the spinner never stops spinning, also so that you can decide whether it should spin only to the left or to the right.
Overall a machine that I really recommend, I hope I can have the honor of buying the next product if you improve it with the above things.
