The Hi-Tech Bullet Collection features two different bullets that can be run simultaneously from the same corded, hand-held controller. It runs on 4 AAA batteries, and is multi-speed and multi-function. The set offers 10 different functions, which are conveniently numbered and printed on the back of the power pack; the front of the controller also offers a light-up display to inform you what feature you are currently running. The functions are Foreplay, Tease, Arouse, Zoom, Wave, Pulsation, Vibration, Random, Racer, and Climax. My personal favorite was Racer, because it featured a very strong, steady vibration. The controller has a slight hourglass shape and is comfortable to hold. You can cycle through the functions with two up/down buttons, one for each bullet; if you cycle past the 10th function, the bullet automatically shuts off.

The kit features two separate bullets, which each plug into the top of the battery pack. They are both made of hard plastic, with a velvet cote. The plastic is easy to clean and body-friendly, but cannot be sterilized, so you should use a condom over the bullets if you plan to share them. The larger bullet is about 5” long and curved at the tip—perfect for insertion and g-spot stimulation, since the motor is located near the head. The second bullet is a smaller 2 1/2” traditional bullet with quite an intense buzz. I found my favorite way to use this set was to partially insert the larger bullet for g-spot stimulation while using the smaller bullet on my clit. This drove me wild and had me orgasming in no time. You can also use the curved tip of the larger bullet for clitoral stimulation while using the smaller to stimulate the nipples.

The Hi-Tech Bullet Kit|Hi-tech bullet collection is waterproof, and there are jelly rings around the tops of the bullets to keep water out. I was comfortable submerging the bullets themselves, but I would advise against submerging the battery pack because of the bullet connectors and the battery compartment.

My Hi-Tech bullets and controller are a lovely shade of translucent purple. The bullets can be run individually or simultaneously. They are quite powerful, and I noticed that running both bullets together does not seem to detract from the power of either bullet. The small bullet is quite quiet, even on higher settings, but the larger bullet can be rather loud, especially on the more powerful settings.
