The GLO Mini bullet from Doc Johnson is a great toy if you need something compact and travel friendly. It glows in the dark, its small, its waterproof, and it is a great travel companion. The vibrations aren't super strong, but its to be expected. Overall, this is a great little bullet.

So Much Potential Wasted on a Buzzy Vibrator
It looks so nice in the package, it feels so nice in your hand, the buttons work great, everything points to this being your favorite toy ever, but the vibrator is buzzy and high pitched and just doesn't feel good, and at the end of the day that's the only thing this toy is supposed to do, buzz pleasantly on your ladyparts. It fails at that, at least if you like rumbly rather then buzzy vibrations.
