Is the Eupho Syn just too subtle for beginners?

I recently decided to jump into the Aneros train, and was able to find the Helix Syn on Amazon for about $50. However, when I recieved the package, it turned out there was a mix-up by the seller and I recieved a Eupho Syn instead of the Helix Syn I ordered. I had read that the Eupho line was more for advanced users but decided against attempting to replace it, thinking it would be close enough.

After some lube troubles (damn you, glycerin), I've been trying it out over the past week, and while I originally felt the peeing sensation that is said to come when the prostate is stimulated, it has faded away recently and I honestly don't think I feel much stimulating occuring on the inside. I can feel the p-tab and very rarely some pressure within, but neither are necissarily pleasureable and I end up masturbating normally with it in, where I can begin to feel it slightly more intensely, but nothing notably pleasurable.

Am I still in the "rewiring" stage and need to just stick through it or should I look into getting another model? I never expected instant results but I keep reading about how subtle the Eupho is compared to others, and I can't help but feel I might get a little more out of a more beginner-friendly model.
