Over and under power stud - double penetration vibrator by Cal Exotics - review by Gracefire

This vibe is primarily for use as a simultaneous vaginal/anal vibe. It is designed for the larger of the two vibes to be inserted into the vagina, and the smaller one to be inserted into the anus. The size is generous enough to satisfy in both areas but small enough that even beginners to the world of anal play will find this vibe easy and fun to play with.

As it is not very compact, I am going to refrain from marking this as travel friendly. In my opinion, it is too bulky for a purse and, while it can technically fit into a backpack or overnight bag, there are other vibes out there that are slimmer and more discreet.

The box claims this vibe is waterproof but I wouldn't submerge it in water. I also don’t feel comfortable bringing it in the shower.

This toy is made of PVC which, unfortunately, only rates as a 2 on the safety scale. Many articles claim that the biggest reason for the low safety rating is due to the inclusion of phthalates in the making of PVC toys. While this may be true of some PVC toys, the box for the Over & Under Power Stud does state that it is phthalate-free.

Upon first taking it out of the box, I noticed a light plastic smell. It was not overwhelming, but it was noticeable.

The shaft of the larger penis has a few fake veins on the surface, while the smaller penis is smooth. In some places, the PVC has a noticeably different texture than the rest of the toy, especially where the two penises meet. It almost feels like very fine sandpaper. It is not enough to stop me from using the toy, but it was enough to mention.

In theory, this toy is a good size. The overall length of the toy is 9.5 inches. It has two shafts - the larger is meant to be inserted vaginally and the smaller is meant to be inserted anally. The insertable length of the larger shaft is approximately 5.5 inches, with a 5 inch circumference. The insertable length of the smaller shaft is approximately 3.5 inches, with a 3.5 inch circumference. The smaller shaft extends upwards from the larger one (forming a "U" shape) approximately 4 inches from the bottom.

The thing that I find most frustrating about this toy is the way it is designed. The two shafts are very close together and not really flexible enough to be pulled apart. An abnormally short (meaning possibly requiring medical intervention) distance between the anus and the vagina in females is one inch. In this toy, there is barely a finger's width of space between the two shafts. This, combined with variation in personal anatomy, makes it almost impossible to insert both vaginally and anally at the same time.

There is a lot lacking in the performance of this toy. It is operated by means of a single button on the side of the toy at the bottom. It has only one vibration pattern, which is a constant buzzing. There are three different vibration strengths: one push on the power button turns it on the lowest setting, another turns it to the medium setting, and the third cranks it up to the maximum power setting. A fourth push turns the toy off. Once you turn it up to the next power setting, there is no way to cycle back down. You must turn the toy off and then cycle back up through the settings to find the one you want.

The vibrations are primarily located in the tip of the larger of the two shafts (which is the one I am assuming is meant to be inserted vaginally), as that is where the motor is located. The vibrations can be felt pretty well down the entire length of the larger shaft but can barely be felt in the smaller of the two. In fact, I couldn't feel them at all, even on the highest setting.

It runs on 2 AA batteries. The battery compartment is located on the bottom of the toy and can be accessed by simply twisting off the bottom cap.

Care for this toy is easy - simply wash it with soap and warm water or a toy wipe after each use and allow it to air dry before storing. If you do use this toy for anal play, make sure to clean it very thoroughly to prevent bacteria from being spread.

Since this toy is made from PVC, it can be used with either water-based or silicone-based lubes. I would highly recommend covering the shafts with condoms before playing, as this should provide a little lubrication and cut down on both the clean-up time. Winning all around!

The packaging on this toy is quite simple; it consists of a box and an inner plastic bag that protects the toy. It is not very discreet as there is a picture of the toy on the front. It can be saved for storage if needed or recycled if not. It would be quite easy to wrap, should you decide to give it as a gift.

The size of the box is generous to accommodate the size of the toy. Including the top hang-tag, the box measures 10.75 inches tall, 3.5 inches wide, and 2.5 inches deep. Without the hang-tag, the box measures 9.5 inches tall.
