This is a fantastic vibrator. First off, the form factor is just great. With its sleek curves, bright color, crisp white, and click-wheel-esque control interface, you might think it was designed by Apple. Really lovely minimalistic design.
In terms of function, it's also pretty close to perfect. There's a decent range of vibration strengths (though I wouldn't mind if it went a little higher), it's reasonably quiet, and the different functions are a nice touch (steady, slow/medium/fast pulse, and wave).
My only real complaint is that to cycle through the different functions, you have to go all the way up or all the way back down to get to the first and last modes. So, for instance, to get to the wave, I have to start it on the steady mode, click up for slow pulse, again for medium, again for fast, and again for wave. I can't just go from the first setting one click down to the last setting. Likewise, if I want to go back to steady mode from the wave, I can't just click up again -- I have to cycle all the way back down through every mode. Doesn't seem like a big deal, but if I could go straight from the wave to steady at key moments...Ahem. That would be ideal.
In the past, I've balked at buying a pricier vibrator, just because it seemed like such an extravagance. After working too much overtime this past week, I decided to treat myself, and let me tell you -- for $50 this is a steal. My other $30 vibe broke down after only a couple of months of light use, it wasn't rechargeable, and it didn't have nearly as many perks as this one. Highly recommend! Every object should be designed this nicely.
