The Cobra Libre II is a better, updated version of the original Fun Factory Cobra Libre. Both of them are rechargeable, completely waterproof (there are no external moving parts, so there is nowhere for water to get into the toy) made of body-safe medical grade silicone and ABS plastic, and the Cobra II has buttons that are MUCH easier to use than the old sensor pads from the original.

The new models have twice as powerful vibrations, and different ELEVEN vibration modes. There are now three buttons on the top that replace the three finger-sensors on the old. Push the "Fun" button to turn it on, the "+" button to increase the intensity and change the modes, and the "-" button to decrease intensity and turn off.

A REALLY cool feature of the new model with its buttons is it has a locking mode. This way you can lock the toy so it will not turn on accidentally while you're traveling, or whatever. (To put it in lock mode, just hold down the "fun" button and the "-" button until the lights on the buttons flash, then it will be locked. To unlock it, hold down the fun button and the + button.)

This new version is also updated for couples play. The man can wear the Cobra Libre while his partner straddles him. She (or he!) can feel the vibrations as well, and has access to the buttons to control the modes.

It is really easy to charge it too, because it now has the "click n' charge" feature that all Fun Factory rechargeable toys have. Just take the charger with the two magnetic tips and click it on to the corresponding tips on the toy and plug it in.

This toy is also incredibly QUIET. Even at full power. It has two motors, so it can be super quiet without sacrificing strength.

Also, Fun Factory offers a 2-year warrantee on all of its vibrating toys.

The only real drawback of this toy is it is not meant as a stroker for the whole penis. Only the tip. But, the tip is the most sensitive part of the penis, so that's kind of the point.
