Joystick of My HeartWith seven different vibration patterns, a positively luxurious finish, and the quality Evolved construction I've come to know and love, you won't find a better deal for your p-buddy!
In addition to the plastic body, a rubber-like material is used for the power control button, which should add to the longevity of the piece. A similar material is also used around the edge of the detachable cap to provide for a water-tight seal. While the metal contacts in the battery compartment seem slightly thin, they're integrated very tightly into the body, so I don't expect to have any issues with them anytime soon.
In the name of smooth appearance and functionality, Evolved made the cap a simple snap-on, snap-off affair, with no clamps, threads, or similar locking features. The downside to this is twofold: First, the cap is a bit difficult to get off out of the box, as the thick plastic (for better or for worse) doesn't have much give to it until it's been worked over a few times. Second, the ridges, while appearing durable, are likely to give way over time, and won't be able to hold the cap as tight as necessary if that happens. As I mentioned, the battery compartment is sealed against water, but the seal itself is relatively small and thin, meaning there's very little room for error before you lose that seal.
Of course, the dreaded breach hasn't happened yet, so I can't keep in good faith and dock it a star. I would, however, mentally file this one in the splash-proof category, rather than water-proof, in consideration of its long-term durability.
On the downside, I found the power to be a bit lacking. Without much follow-through, some of the patterns are more of a tease than a booming percussion. It feels strong enough in the hand, but the power just doesn't translate on the field. The issue, more than likely, is simply the fact that the vibrations from the motor pulse with almost perfect uniformity throughout the entire toy. While this offers the opportunity for additional stimulation of the perineum, I feel as though a lot of the power is wasted by this design.
