This is quite possibly one of my favorites so far. When I got it in the mail I was so excited! I opened it up and immediately used it, I'm in love! This is definitely going to be a favorite in the toy box now. It's extremely good vibration for being such a small device, and it hasn't eaten through the one battery I've put in it so far, I'm always happy with something that doesn't guzzle batteries!

Let's hop to the good about this item:
It only requires one AA; I'm always a fan of things that don't require many batteries.
It offers quite the amount of vibration for being so small and only using one battery. It has 10 different modes and is quite the little trickster.
You get 4 different caps to use with it, so you get variety added to the variety already offered with the modes available.
It's waterproof.
The material doesn't smell funny at all, doesn't have an odor, and doesn't retain any odor.
Cleanup is a breeze, just use soap and water!
It's very small, travel friendly, and easy to hide.

The downside:
There are two caps that are more dome shaped and are further away from the three beads that vibrate. For one, they don't vibrate well, and for two, the one is rounded and just didn't do anything for me. The other is spiked and hurt more than anything else.
There are two caps that come with it that are closer to the beads and therefore vibrate well. I recommend using those caps and have found that I enjoy them both really well!
I wasn't a fan of my entire hand vibrating because the pocket rocket didn't concentrate the vibrations all that well; but, as I said, it's strong so that didn't deter any of the vibrations, it was just a personal dislike because my hand was all shaky!

10 functions/use;
This toy has 10 functions on it, to use it you just put a battery in and slide the toy shut, click the middle part to where it says "On", this will not make the toy actually come on, it just sets it to where when you hit the "functions 10" button it will begin working.
The 10 functions/modes are low constant vibration, medium constant vibration, high constant vibration, high constant pulsing, long pulse-short pulse on higher vibration, 2 short pulse-1 long pulse high vibration, low vibration pulse building to high vibration pulse, steady build up to medium-pulse-continue to high vibration-pulse-off then cycle again, vibration builds steady from low to high-pulses-descends from high vibration to low-pulse-start again, pulse builds from low vibration to high-then builds steady from low to high vibration

Now, onto the material;
It's non-porous, and doesn't retain odors, nor does it have an odor. It is simple to clean with warm water and soap, and it does not absorb lubricant or body fluids.

Clean-up;
I recommend a toothbrush if you're going to use the spiked caps. It helps to make sure you're cleaning in between all the spikes. Also, if you use the massager without the caps, you might want one to scrub between and on the three beads too. That can get a little tricky.

This is still an absolute favorite of mine. Especially during the monthly friend because I'm not too fond of internal stimulation during that time. I also like to just play with this on days that I'm just not wanting to go the whole 9 yards to masturbate or have sex. This one has only gone through one set of batteries in 2 months, and that's with a lot of use. I'm absolutely happy with this and it will stay in the toy box for a while!
