The Unleashed features seven vibration settings - three constant levels and then four different patterns. The patterns are great - lots of variation from low to high with fervent intensity. I personally find that wireless eggs do best when vibration levels are changing - constant buzzing gets dull and ignore-able very very fast - so I am very pleased with the variety of patterns available in the Unleashed. The remote works to cycle the egg through the seven functions through a single button. There is also an on/off button. There is a light up screen that visually shows what pattern is happening through illuminating different parts of a flower image. I find this a little strange, awkward, and unwieldy, but hey - it works. If the remote's battery dies while the egg is on, the egg keeps vibrating and must be opened up itself in order to have it shut off.
The remote takes 1 12v 23A battery, and it kills the battery when left on standby so be sure to remove it when not in use. It's a goofy battery and ran out pretty quickly, allowing only two casual play sessions before I found it dead. The Egg takes 2 12V batteries, and does not seem to consume those voraciously.
