The vibrator is "one speed fits most" with a slide away top exposing the recharging plug (adapter included) For relatively standard couples' play it is a great toy, but as a solo masturbation toy it lacks the power needed to add meaningful sensation.

As mentioned it, as a tool for mutual pleasure the Bo is stellar. Though this does not replace vibrators or cock rings that are purer in purpose the Bo is a fun tool to add to anyone's arsenal. During standard sex with positions facing one another it is great for couples, and its flexibility enables even the novice to have fun without fear of injury.

The ring portion is a soft and flexible rubber that provides a very light touch, yet still manages to assist with an erection as a cock ring should.

The vibrating portion is covered in soft material, but has a hard inside. Its width enables it to contact the clitoris without so much focus as to be distracting.

If one is looking for a tight feel this may not be the toy for you. It gives very easily and can be stretched over the testicles to fit below the scrotum holding the balls tighter against the underside of the penis. For many men this is an odd feeling, and though suggested in the Bo's instructions I do not recommend using this toy to replace a ball-stretcher or similar device.

One speed vibration limits the toy's usability, but the overall design and usability is well worth its limitations.

Care instructions are included and are fairly standard. The ring section separates from the vibrator for easy cleaning. Both sections can be housed in the Bo's small plastic case which has an opening on the side for the recharger.

Packaged beautifully. This could easily be given as a present with only the need to throw a bow on the black box.

I have thus far had a good deal of fun with this toy. As said before, this is not the end-all-be-all of vibrating cock rings or sexual aids, but it has all of the right attributes to be a welcome addition to my kit.

It has impressed me enough that several of these will be going out to my friends as holiday presents.
