The Gee Whiz is a vibrator accessory, meant to be used with personal massagers like the Ideal or the Hitachi Magic Wand. Placed on the top of the massager, it provides vaginal/anal stimulation and vibrations that travel through the silicone cap.

It has an insertable length of 4" with a nice curve, and a circumference of 4 1/2 inches

I found that the Whiz muffled the sound of my loud vibrators--which can be really helpful for people that have issues with their massagers being too loud for regular use.

The Gee Whiz is made of non-porous silicone, no latex or phthalates involved. It's a marbled blue color, that looks like it belongs on a piece of glass, not your vibrator.

However, because of the soft, slick silicone, this thing is a dust/hair/anything magnet. Within one use, I had picked up lint, dust, hair, and glitter--and I didn't use glitter anywhere near the Gee Whiz!

The Whiz is on the softer side, bendy and pliable, but not too squishy that it didn't serve its purpose.

There is also a textured nub that is supposed to rub against the clit.

When I first held the Gee Whiz, I was surprised at how hefty it was! The design is really impeccable, I used the Whiz with both the Ideal and the Hitachi Magic Wand, and it fit snugly on each of them. My only concern was that it would pop the heads off the vibrators when I removed it, so I had to remember to break the seal before I yanked it off after use.

The insertable portion of the Whiz is about 4 inches, which for some may be a little lackluster, but was not a problem for me. My issue was that I was never really able to line up the textured nub with my clitoris, leading to somewhat disappointing clitoral stimulation.

I had different results with each vibrator that I tried the Whiz with. First I used it with the Ideal. It was a perfect fit, covering almost the entire head of the Ideal. Unfortunately, the Whiz muffled the vibrations of the Ideal so much that I was left a little unsatisfied.

I decided that I would try it with the ever-powerful Hitachi Magic Wand. Again, I had no problems with the fit, though it covered less of the Hitachi's head than the Ideal's. The Whiz and the Hitachi were a match made in heaven--the extra strong vibrations of the Hitachi, paired with the penetration of the Whiz meant that I had a dual clitoral/vaginal orgasm in under two minutes. My partner and I were stunned at how well it worked, considering how unimpressed I had been with it the night before. Because the Hitachi's vibrations are so strong ordinarily, the dampening of that by the Whiz meant that I got just the right amount of vibration, without sacrificing the power I needed.

Because the Whiz is made of silicone it can only be used with water-based lubricants, other kinds will cause the material to deteriorate. However, it can be totally sterilized! Boiling the Whiz for 3 minutes, or putting it in the top rack of your dishwasher will make the whiz good as new, and sanitary for anal use, or for sharing with a partner. It's recommended that you keep the Whiz in the round package it comes in, so as to maintain the shape. I'd recommend this, as well, because dust is so attracted to it and keeping it in a sealed container will minimize the problem.

The Whiz itself is water-safe but if the toy you're using it with is not waterproof, make sure you're using it on dry land!
