Waka-Waka-Waka-WakaFou is a solidly built toy that will work well for a number of people. The controls are easy to use, and the unique design works very well to cup smaller areas and provide relatively strong indirect vibrations. Unfortunately, the plush silicone collects lint and dampens the vibrations some, but as long as you're not looking for a powerhouse this shouldn't be a big problem.
The color is also bright and vibrant, if you get the yellow. It's comparable to a fluorescent yellow highlighter. Seriously. Some are going to be a huge fan of that, but others might want to go with the red instead.
The open mouth is the unique part of Fou's design. Just sitting there, it measures about 1 1/2" across and 3/8" tall. However you can squeeze the mouth shut and have the edges touch, or you can pry it open a bit to stick something wider in there to be cradled by vibrations.
To anybody unfamiliar with FunFactory as a brand, Fou looks like it could be just another egg shaped piece of art. You can easily pass it off as a massager of sorts though if anybody does happen to notice it. The unique design lends itself well to being asked about, so don't leave it out if you don't want to answer "what's that thing that looks like Pacman?"
There are three buttons located on the top, surrounding the logo in a triangular pattern. The + button turns Fou on and cycles up through the vibration strengths. Something that's neat is that once you max out on strengths, the backlight blinks continuously to let you know there's no more to go. Pressing the - button will cycle you down through the vibrations and turn it off. Pressing the little * button will start the vibration patterns. These feel like they only have one speed, but it was hard to tell for absolute certain. The solid vibrations are a lot easier to tell the difference between with the lowest feeling moderately strong and the strongest being finger numbing. They're also a bit on the loud side as well; not being able to rival the Hitachi in sound but definitely loud enough to hear through a closed door on the highest setting.
The vibrations are the type that feel really strong in your hand, but then in use don't quite seem to live up. That's most likely due to the very plush silicone, which seems to serve to dampen some of the vibrations and make them feel very surfacey when you get them through the edges of Fou's mouth.
On the plus side, Fou is completely waterproof so you can bring him into the bath or shower with you. So far, he's held up just fine to shower use and a submerging to clean.
To store, just toss in the handy dandy storage pouches that FunFactory has included!
As far as giving as a gift, it definitely shows what you're giving (if you don't ditch the outer sheath), but it's not tacky at all either.
I did enjoy being able to cup my clitoris during solo play and during sex. Surprisingly, Fou didn't seem to get in the way that much. A bit more than MiMi, but nothing horrible. In doggy style sex, the size difference was negligible. It's a very unique design that may grow on me, but may not. Fou is overall well made though, and while not perfect is still a solid toy.
