This little cock ring vibrator is incredibly powerful! Not only does it have a low, medium, and high vibrations (that are a part of the 9 vibrations setting), but it also has different pulse vibrations to change it up and vary your experience if you're wanting to try something different. The cock ring itself, is silicone covered, which feels nice and silky against your skin. The vibrations are stronger at the nubs than it is in the middle of the toy, however I can't tell if it has small vibrators in the nubs and in the middle of the toy or just the middle. Regardless, this will feel great on BOTH of you.There does not seem to be any sort of openings on it, as the charging port is actually magnetic-- meaning, that nothing plugs in, but instead connects and stays fastened via magnets (I know, how do they work? LOL). This toy comes with a remote control that can be synced with the toy and used during play, but the best part about the remote is that it doesn't HAVE to be connected; you can play with no remote! [Pictured is the toy in the box, while mine DID come with a remote, I managed to lose it during/after play.]This little thing is super powerful (not sure if I have reiterated this enough), and holds a pretty strong charge even an hour and a half into use! It's not like those other rechargeable toys that immediately start to lose their strength within 30 minutes. Plus, this should fit most girths, and if you're larger, it is has some flex, so you should be able to fit it as well! The only problem we had with it, is that in missionary it slipped off a couple of times due to vigorous thrusting, however, that was just due to the vigor of the thrust.I absolutely recommend this toy to anyone thinking about purchasing it. You may be skeptical that it's under $30, so how good could it be? But seriously, this toy is fantastic and I will be using it until it dies!My husband hasn't used it just by himself yet, so I will update when that happens to see if it's more of a couple's toy or if it works well as either a single person or a couple toy. As for it being a vibrator for solo play for women, it most definitely should work as a solo toy! You could even get resourceful with it, for more fun!Seriously, buy this vibrating cockring. It is so comfortable, smooth, powerful, and just the absolute best value for the money!!
