Fun Factory Stronic series

I've only seen a few posts on here about the Stronic series and am interested in getting one for anal use. This one is thickest, but doesn't have as much of a curve so I'm not sure it would hit the prostate as desired: https://us.funfactory.com/en/pulsators/bi-stronic-fusion/. This one is specifically made for anal use and prostate massage: https://us.funfactory.com/en/pulsators/stronic-zwei/. This one also has a pronounced curve, but also has ridges for additional stimulation: https://us.funfactory.com/en/pulsators/stronic-drei/. I've found mixed reviews of the latter two mentioned above, but am leaning towards trying the Drei if I can get it with a reasonable discount. Does anyone here have experience with any of these, especially for prostate massage? I'm interested in something new that doesn't rely on vibrations or manual movements.

Thanks

That prostate massager looks incredible. I hope someone here has some experience with one of these - I'd love to hear about it.

I was able to order the Stronic Zwei at a massive discount (paid under $115). I should get it early next week and will provide my feedback. Can't wait!
