The controls consist of three "feather-light" buttons located at the "front" of the toy's base/handle. These buttons light up when the toy is on and click most reassuringly to inform you that you have successfully pushed a button. The buttons are easy to push, but it's definitely possible to hit some buttons by accident.
The bottommost button is the power button. One click of this button turns the toy on, and you'll know it's on because all three of the buttons will light up, but no vibrations will start automatically. Another click of this button will turn the toy off, no matter what function you're on; handy for those "emergency off" situations.
The second button controls the seven settings for the clitoral stimulator. The first three settings are steady vibrations of increasing speed. Even on lowest speed, the toy can be heard clear across a medium sized room. The highest speed is a rather loud, high-pitched buzz. The next four settings are a variety of pulsations, including an escalating setting. After the last setting, one more click of the vibration button turns the vibrations off.
The last and topmost button controls the three speeds of rotation for the shaft. Again, even the lowest setting can be easily heard across the room and probably through a closed door. It's more of a whirring noise that reminded my roommate of a massager and me of a hand-mixer. Definitely not discreet, but on the upside, I don't think many associate "hand-mixer noise" with sex toys, so you may be in the clear. The upper half of the shaft does the most rotating, as that is where the rigid mass in the center initiates the rotation. The shaft's rotations are meant primarily for vaginal stimulation, but on occasion the shaft can bump into the cervix, causing a bit of discomfort. Proper positioning of the toy will prevent this from occurring.
Loading and unloading batteries is simple enough. The cover to the battery case is a locking cap. To open, simply grip the middle ridge of the cap and twist counterclockwise; the cap pops free. Inside is an easily removable (just turn upside down and it falls right out) battery case that holds three AAA batteries. Stick the batteries in as directed, put the case back in with the metal bits going in first, and line up the nubs on the cap with the notches, twisting clockwise to lock in place.
How does one use a noisy, indiscreet toy such as this one in a relatively non-private living arrangement? Take it into the shower, of course! Unfortunately, this may be less successful for those of us who have weaker water pressure in our showers and whose showers are, as a result, less capable of muffling the hand-mixer sound. However, if there is a relatively noisy shower in your vicinity, you're in luck. The Cashmere is waterproof! Well, sort of...
I took Cashmere into the shower multiple times. Each time, it performed very well; no funny business. On top of that, the sound of the shower effectively nullified any and all noise the Cashmere made. However, when drying it off post shower and removing the batteries, it is revealed that water can seep into spaces directly adjacent to the where the batteries are housed. While the cap is still closed, a watertight seal is formed between the waterproofing ring and the cap. However, once the cap is opened, the moisture is free to go wherever it wants, so make sure you turn the Cashmere off before you take off the cap or disaster could result.
Great review!
