Hey @shinobi1987 , I'm obviously biased since I'm one of the creators of Haptics Connect, but if there are any issues then I'm here to help.
As for the toy itself, if you want to go for a vibrating toy, I would say I prefer the Gush over the Calor. It has a better fit which means the vibrations do feel better to me.
There are multiple playback modes inside haptics to change how the toy reacts.
The vibrations do feel immersive, but as @RealcumberScripts says, a stroking toy would be the better option if you want to go for realism.
