The Gee whiz is a hitachi attachment and could be used as a stand-alone dildo but that would be wasting it's talents. When attached to the hitachi, the gee whiz makes any hitachi a fantastic dual stimulator. The slight nub that looks completely useless, positions right on the clit while the insertable length provides all the pleasures of penetration. For those that need more than just clitoral stimulation, the gee whiz provides that extra little oomph. Since the hitachi is fantastic for both couple and solo play, the gee whiz by extension would be great for both as well. The gee whiz might also have the added bonus of being visually stimulating for your partner.

The silicone body of the gee whiz makes it a gem to clean. The lack of ridges and bumps is also great since those often become a trap for all sorts of nasties. There was no smell coming out of the package which is a welcome reprieve from other toys. The one thing to note is that the gee whiz is one of the few toys out there where the smooth texture works against it. The gee whiz is not particularly wide and without any texture, there is barely any stimulation past insertion.

The Gee whiz is 7 inches with an insertable length of 4. It has a circumference of 4.5 inches yet somehow feels thinner than that. The size might be acceptable for a beginner and usually would be for an advanced user, but the design and texture takes away from any size or girth it may have.

The gee whiz is, however, incredibly well-made. It feels like a quality product and its incredibly beautiful in its simplicity. The swirl of blue is tasteful and is a nice break from the intricate, but pointless designs of other vibrators.

There is one particular problem with the gee whiz-- it slips out. Since the vibrations from the hitachi are so strong and the gee whiz is so smooth, it often slips out. Even if it wasn't slipping out, it felt like it was. Holding it in place is an option, but your hand is guaranteed to be numb from all the vibration. The gee whiz is supposed to provide g-spot stimulation but... it didn't and there is another attachment out there for that particular purpose.

Silicone is super easy to care for and clean. Soap and water always does the trick. Remember to avoid silicone based lubes.

The gee whiz comes in a cylindrical plastic container. It's a great place to continue storing the gee whiz and it makes for a great gift.
