Penis Vibrators, aka guybrators, are toys that vibrate, rather than stroke, the penis. They can also be used as strokers, but it's not their specialty, they're made to just pulse and ruble you to deep orgasms.
By vibrating deeply, these toys shake your shaft all the way to your core, and stimulate your prostate. This makes orgasms more intense without having to go through the anal route to prostate orgasms. Or it can be combined with prostate stimulators for a doubly intense orgasm.
These aren't to be confused with vibrating cock rings, which are close to the base of the cock, not the tip.
Hot Octopuss Pulse III
The Pulse is a strong penis vibrator that looks like a spaceship for your cock. To use it, you get inside the 'wings' and place your frenulum (the underside of the tip) against the raised circle. From there you can control the 5 vibrations patterns and 9 speeds until you come.
The vibrations are powerful and deep, more rumbly than buzzy, so it really shakes you all the way to your core. I'd call the Pulse a penis rumbler as much as a penis vibrator.
Cobra Libre II
The Cobra Libre is a vibrator completely wraps around the tip of your penis. It's got 11 vibration patterns, 3 more than the Libre.
Once it is around the head of your penis you can let it work its magic until you come. The velvety inside is soft and you can also twist it and gyrate it around your tip for even more sensations.
Pocket Pulse
Price: $85
The Pocket Pulse is like the Pulse III, except smaller and lighter so it can fit in a bag or purse. Even though it's smaller its still got those deep rumbly penis vibrations. The downside is it's 75% the strength of the Pulse III Duo at its max setting.
The material is a smooth and soft silicone that is easy to clean, since it's water proof, you can just rinse it off under the faucet when you're done.
Manta
This penis vibrator has a different shape, and is an awesome couples toy.
During sex, it works kinda like a super powered cock ring. The 6 patterns and 6 speeds let you amp up each position, and it is amazing for blowjobs.
It also works for solo masturbation too. The ridges are soft and hold lube well for penis stroking and vibrating at the same time.
Best Cheap Penis Vibrator
Price: $21
The cheapest penis vibrator I could find was the Adorime on Amazon. It's made of silicone, has 10 different vibration settings, and sold as a 'stamina trainer'.
It's not as powerful as the other vibrators in this list, so it might not be able to make you climax if you need a lot of stimulation. It's also not water-proof, so be careful to keep the button and charging port out of the running water when you clean it.
Are Dick Vibrators a Good Match For You?
Penis vibrators are more effective for some people than others. If you have a sensitive cock, and can come from a few minutes of masturbation, than there's a good chance you'll love penis vibrators, which edge you wonderfully into deep orgasms.
But if you need 10+ minutes of stimulation to come, then penis vibrators might not be enough to make you ejaculate on their own. In that case you'd be better off with a fleshlight or another male sex toy (read that guide here).
Even if it's not strong enough for climaxing, penis vibrators still work wonders for foreplay or in combination with other toys.
