Which model should I try next?

I’ve had the prograsm ice for 6 to 8 months now. While I’ve had fun with it and it’s give me some great sensations and powerful traditional orgasms, I can’t say it’s ever given me the full hfdo.

I started with this one because I thought I’d enjoy the fuller feeling. While I do enjoy it, I feel like I’m still not where I want to be.

For anyone that took a similar path and started with the prograsm like me, which model did you move on to second? Did it work for you or did you have to try a third? What model do you guys recommend I try next?

Edit: perhaps there is something I can do to make the progasm work better? Like a technique or modifications?
