I'm curious about this. I expect that the traditional has better movement but that the syn models are more comfortable. I'm just curious which has worked best for all of you
I got a knock off helix, and a aneros Eupho Syn, I feel the Syn is so much smoother and easier to use just feel more comfortable. The normal one I feel it’s better if someone used it on you and the Syn used by yourself
I also prefer the Syn models although the Progasm series is equally good! Prefer the larger size - just recently acquired the Nexus Revo Extreme which has a rotating head and vibration along the perenium. Has given me some really good super Os with lasting intense pleasure. The head is large enough to pop inside and stays in place. I use plenty of lube - this one will turn you inside out with your prostate begging for more!
