CEN didn't really try to break the mold with this one. In fact, the Rechargeable beaded dolphin lacks the satisfying pulsation modes that most of their rabbit vibrators seem to have. This version has only 3 levels of steady vibration that fall short in nearly every way. not only are they subdued by the firm jelly, but they seem to be rather high-pitched as well. This only increases as does the strength. The lower setting is definitely deepest but the higher two settings don't offer much more. I was disappointed because bullet size frequently gives me a good idea of vibrations size but the jumbo sized bullet really seems to be fighting with the stiff jelly. I am almost positive that this bullet would be stronger were it free of its jelly straight-jacket.
This vibrator offers rotation of the upper half of the shaft. Unlike some rabbit style vibrators, the flexible wire inside can't really be bent in part because it's not very long but also because it's surrounded by thick jelly. The rotation is really quite mild but pleasant, for me. Pleasant enough for me to squirt but, then again, that's pretty easy these days. The direction of rotation can be changed as well, to offer a change of pace or send you over the edge.
The lower half of the insertable portion of the shaft hosts 5 columns of metal ball bearings, 8 rows deep for a total of 40 beads. Each column is on a wire and there is a little room for the bearings to move up and down (just a few millimeters) and the whole piece moves together, at the same pace. I think the Rechargeable beaded dolphin has more beads than I've experienced with other rabbit vibrators but because they all do exactly the same thing, it's not quite as exciting. Additionally, the beads take up nearly 2" of space which makes almost half of the shaft quite rigid. It's like a metal wall and when I angle it toward my G-spot, can become painful. The pleasurable sensations seemed to stem only from the rotating shaft.
Because the beads and rotation are controlled by the same button, they both operate at either high, medium or low. I don't generally require more than one speed for rotation but I did find the beads to be easily stopped by clenching on the lowest setting. Medium and high definitely perform better.
Including the button which changes rotation, there are 3 soft plastic buttons (rotate, vibrate, direction) which are fairly raised from the base of the toy, like remote control buttons. They're easy to find and labeled with the words "Rotate," "Vibrate" and arrows around the button direction control buttons, respectively. There are also 3 red lights above either up/down button to indicate which setting the toy is on but I can never see those buttons during use so I could give or take that feature. I do wish there was a master power button, however. The separate controls require turning on the functions separately and there is no way to quickly turn it off in case of emergency or interruption.
I have noticed that there is some lag between turning on the functions and them kicking in fully. The rotation/beads are a bit slugging for the first couple seconds and it takes the vibrations a second to "jump" into action. The jump can literally be felt. I think that having the other function on causes a slightly longer lag, but only by a fraction of a second.
This vibrator is kind of noisy and definitely could not be used with someone else in the same room (if discretion is the goal). A closed door would probably be safe but I'd add some white noise (TV, radio, fan) just to be safe.
Of course, the charging base doesn't do anything special. It just charges and the the base of the vibrator slips into it fairly easy. Each piece has an arrow to indicate position so the metal contact points will meet. There is an indicator light which seems to flash red and green when charging, then stays green when the toy is fully charged. The first charge needs to last 6 hours (although the light went off well before 6 hours and it was not ready) and the packaging advertises 75 minutes of use. I cannot fully vouch for that because I simply do not want to use this toy for very long but the power has stayed consistent during my use. Following charges need take only 2 hours, I believe. I misplaced the instructions but they do say not to charge for over 24 hours so this vibe cannot be "stored" on its dock, unfortunately.
