The battery cap is located at the base of the toy. To open the compartment, the bottom/lid has arrows showing you which way to twist to open or close. You can see this in my photo.
The battery holder slides out of the compartment to make it easier to insert the batteries. It takes 4 AAA batteries that are not included!
Buttons and controls
At the base of the toy, right under the bunny, is the control pad. There are 4 squishy green buttons in the shapes of hearts. Beside them, you’ll notice words telling you what each button does.
The buttons are not easy because they don’t click or light up, and you have to push them hard to work. It’s hard because I often have to use both hands – one to hold it and the other to push the button. They aren’t sensitive.
The first button is on/off button for the rotating shaft and beads. When you press it, the shaft starts rotating to the right and the beads start spinning in the same direction. Below that is the R/L button, which stands for rotate left or rotate right. Pushing that button once causes it to rotate left. To turn the rotations off, you’ll just press the top button “on/off.”
The third button down says “on/off.” This button works the vibrations of the bunny. When you click “on/off” the bullet inside the bunny shape starts vibrating on low, the first setting. When you click it again, it’ll turn off.
The button below that on/off is the “Hi-Low” button. Pressing it will just cause the bullet in the bunny shape to go up one speed. There are only 2 speeds.
Also on the control pad is the word “Waterproof,” so you won’t forget that it’s waterproof. And if using a rabbit vibrator in the water is your passion, then this is definitely waterproof!
I was nervous about submerging it, but I've been able to do so without the least bit of water ending up inside. The only worry I'd have about using this in the water is that it looks like, over time, where the TPE is glued to the base, it could come loose and water might make its way inside the TPE. I don't think it'd be good if that happened because it could get to the bullet and that may mess it up. I was looking at where the TPE is glued to the base and it does look loose already and I haven't had it for over a week. Just something I personally worry about.
Vibrations
The only vibrations are in the bunny. The first setting is low, but enough to be felt easily. The second is more intense.
I can't say I'm very impressed with the vibration selection since there are only two speeds and both are pretty weak. I have a sensitive clitoris and can't seem to get there using this alone. I either need to switch to another, more powerful vibrator after 30 minutes or just use this as a fun "massage" with my partner before intercourse. So far, this is how I've used it and it is enjoyable, but a rabbit vibrator is more designed to be the real deal, something that delivers, so that is a bit disappointing.
The vibrations are located in the bullet that's inside the bunny shape. I can see the ears jiggle a little when it's on the highest (second) speed, but they aren't very noticeable. It seems the vibrations are felt the most right in the bunny's head, so pressing the head against the clitoris provides a little more stimulation than the ears. Unless you're very sensitive and like a slow build up, then I think the Sophomore Bunny will be a bore. It's a fun toy and definitely makes a great foreplay or teaser toy, but not an orgasm machine. The vibrations, being so weak, don't cause me to go numb, so that allows me to feel oral afterward, but I'd have loved to get further using this.
The strongest vibration is stronger than a cell phone's vibration, but not as strong as most vibrators available, including many bullets. My RO-120mm bullet is probably twice as strong as this, if that tells you anything. The vibrations aren't very high pitched or buzzy, but that's likely due to the weakness of them.
I can appreciate the quietness of the Sophomore Bunny. The Sophomore Bunny isn’t terribly loud. The rotation causes a lot more noise than the vibrations. It can hardly even be heard from under the covers when it's on the highest speed and the rotation is on. To be totally safe though, a cover and some background noise like an air conditioner or TV will be enough to hide the noise. It can't be heard at all through a closed door. It would be ideal for those with roommates.
I do enjoy the rotating function, especially since it's about the only feature that stimulates me enough to keep me from dozing off. The entire shaft from tip to the bottom of the beads rotate. This, combined with the somewhat thick, g-spot curved tip does provide stimulation to my g-spot, and I feel most people who have located and are able to stimulate their g-spot with similarly shaped toys will notice stimulation there. When inserted just past the beads, it presses pretty hard on my g-spot. So much that if I have the urge to urinate, it feels like it's pressing my bladder.
I described the sensation to my partner like "a slow clitoral and g-spot massage." That sums it up for this toy. The rotating g-spot tip goes in circles so it kind of slowly massages the walls and the g-spot when it arrives there. The rotating also causes the bunny to move a little on my clitoris, which is the only reason I get anywhere with this toy -- the g-spot and clitoral rotation.
