Aneros EUPHO SYN is easily one of the best prostate stimulators I’ve ever put in my butt. If it wasn’t designed so differently than other stimulators, I could say it’s the best but, really, it’s in a league of its own. While I find the price to be a bit high for suck a small amount of materials, I think the price is justified by the high level of design and thought put into the device. If you like prostate play, meet your new best friend.
