Water missile probe is an anal vibrator by Cal Exotics. Even though it is designed for anal stimulation, I found this toy to be good for vaginal penetration also. It is waterproof so you can take it with you in the shower. The vibrations are mild compared to more advanced toys, but it still worked great for me. You can also use it for stimulating the clitoris and nipples; the vibrations range from low to high and are very enjoyable. The tip, however, might seem a little intimidating to the beginners, but I think both advanced and beginner users can enjoy this vibrator. It works great for solo play and can also be used with a partner.
Even though this toy is sold as an anal vibrator, it doesn't have all the features of safe anal toys. There is no flared base so you would have to be careful not to lose the grip on the toy. However, the long shaft makes it comfortable to hold.

Water missile probe is made out of plastic. It rates 8 on material safety. It is non-porous, hypoallergenic, latex and phthalates free. There is no smell to the toy. The material overall is hard to touch but it feels very smooth, which makes it great for anal stimulation. However, due to the design of the toy there is a line at the base of the tip going around the toy. But it didn't really bother me, since it I didn't feel it during use. The material makes this toy easy to clean and take care of.

The vibrator is tear shaped: the tip of the toy is oval shape and it becomes more narrow towards the middle and the end, making the shaft comfortable to hold. The shape is perfect for anal play, even though the tip might be too big for some. The toy is 6 1/2 inches long, the oval tip is around 2 1/2 inches long and the shaft is around 4 inches long. The product page, however says that it is 5 1/2 inches long. It is 5 1/2 inches insertable. It is 4 inches in circumference around the widest part of the tip. The shaft is 2 inches in circumference at the narrowest point. I think this toy would work great for somebody who already had a little bit of experience with anal toys. It comes in one color - kind of like metallic baby blue. I actually really like the color. It is easy to hide and store. I think it can be suitable for travel.
Here is the toy compared to a marker:

This vibrator uses a twist base to control the speed, ranging from low to high. The vibrations are spread throughout the toy but they are more intense at the tip. The vibrations are powerful, even on low and medium settings. The toy worked great for me underwater also. It is pretty loud, but you should be fine behind closed doors.

The toy runs on two AAA batteries. The instruction actually come inside the toy. However, they are wrong! You need to do the opposite of what the instructions say. At first, I was frustrated because it wouldn't turn on, but then my friend put the batteries an opposite way and it worked fine. Confusing, though.
Do the opposite of this:

This toy is very easy to take care of. It is waterproof and there is a rubber lining protecting the battery compartment. Just make sure to screw the cap on tight. You can wash it with water and soap or use toy wipes. It can be used with water, oil and silicone based lubricants. The packaging, however, advertises water based lubricant for "maximum pleasure".

It doesn't take much space, so it is easy to store. I keep it in my bedroom drawer, awaiting long-wanted toy box.

The toy came in a simple plastic packaging.

I was thrilled when I got this assignment, since I was looking into expanding my collection of anal toys. I was looking for something simple, with enough power, and waterproof. The water missile probe worked out great. The vibrations were enjoyable and, even though, I was a little intimidated by the tip, it went very well with lube. It is very easy to hold in place even in the water.
