It seems like most vibrators tout their power. I'm looking for the opposite: a vibrator that will work reliably at the low-end of the scale. My wife doesn't respond well to a strong vibrator. The one vibrator she likes is still a challenge because it is nearly off at the level she likes it - and easily turns off as a result.

Is there a vibrator out there that is designed to have a wider range of settings at the low end?

Thanks in advance!
