Hey @Gazzoid
I’ve owned the Nexus Revo Intense for over a year without any issues. You can sit on it and rock back and forward while in operation but it is heavy and it can be frustrating if it slips out
I also have the Nexus Revo Embrace. This is more lightweight meaning the massage is less ‘intense’. However the genius of this offering is that it is connected to a cock and ball ring, which not only helps stay hard but also helps keep the massager where it needs to be.
Neither are cheap but if you have the money I can recommend either, or both. If you are interested, I have reviewed both on the main site.
The Stealth looks like an upgraded Intense with remote control, which works well with the Embrace as the buttons on the Intense can be a little tricky to get right
Hope this helps
