There's a lot to love about the Gee Whizzard: it's made of pure silicone, it harnesses the awesome power of the Hitachi Magic Wand, and it can be used either for insertion or external use. It has a slim g-spot attachment on one side and a bunch of nubs for clitoral stimulation on the other. It's an extremely versatile item. You get about 5 inches of insertable length for the g-spotting end and about an inch of diameter, so it's not a huge toy. The silicone is extremely squishy and floppy. It's clear with pretty green swirls throughout.

The Gee Whizzard slides pretty easily over the head of the Hitachi. The idea is that you can either use backside with nubs externally, or flip it around and insert the g-spot attachment. Then, you switch on the Hitachi and vibrate yourself to orgasm. That's in theory. In practice, it works out pretty well, since it's kind of hard not to orgasm when you're in the vicinity of a Hitachi, but there are some hitches.

Personally, I found the attachment a little too floppy for g-spot stimulation. As powerful as the Hitachi is, I couldn't really feel the vibrations internally when the Gee Whizzard was inserted. As you can see from the accompanying video, the Gee Whizzard doesn't do much to muffle the noise of the Hitachi, but it does diffuse the vibration intensity a little. The nubs on the backside, when used on the clit, felt pretty nice, but since they're on the back, it was a little awkward to apply pressure. There is a little bit of texture on the g-spotting end, but it's too subtle to be felt.

Since the Gee Whizzard is silicone, cleaning is a snap, which is especially nice because the head of the Hitachi isn't made of a sterilizable material. So you can remove the cap and sterilize it if you want to share your Hitachi with a non-fluid-bonded partner. Cleaning is the same as for any other silicone: boil, top rack of the dishwasher (no soap), or a wipe-down with 10% bleach solution.

All in all, I think the Gee Whizzard is great for protecting the head of your Hitachi from bacteria or other pathogens. It would be great for someone who doesn't need a lot of firm pressure for g-spot stimulation, or someone who is sensitive and wanted to tone down the Hitachi intensity a (small) notch. Additionally, the Gee Whizzard ought to fit onto any wand-style vibrator that has a head the same size as the Hitachi, which is pretty cool. The Gee Whizzard could be used for anal play safely, since as a base it has, well, the entire Hitachi.
