Yes, it is. The Cord-Free works flawlessly, but that's purely on a software basis. The Wii reads the nunchuk fine; it's as responsive as when connected normally. The hardware is where things get messy.
The Cord-Free looks tacky. It’s a plastic molding of the bottom of a nunchuk attached to a grey base with flaps to cover up and hold the cable. It does hold the nunchuk upright and in place, and if tied correctly only a small portion of the cable is visible, where it plugs into the outside. And there is one right way to tie it so that the least amount of cable sticks out. We don’t like the extra plastic piece attached on the bottom and we don’t like the flaps. It just looks cheap.
The very cheap looking bottom. It works, but looks are something too, you know.
Much, much more importantly is the inability to use the plastic glove for the Wiimote when using the Cord-Free. Or presumed inability, because when it arrived and we tried putting the receiver on the Wiimote while the sleeve was on, it didn’t work. But you can put both on, technically, by fitting it under the sleeve. Yes, it'll stretch it, but it fits. It's too early to tell if it'll leave the plastic sleeve permanently stretched to the point of damage, but after wearing it for a few days straight it’s barely stretched.
We are very pleased with the battery life, connectivity and use in general. Our tests show that while it doesn't actually improve gameplay, it does give players a psychological edge of sorts. In our playtests, we found most people felt more confident with the controls in games such as Wii Sports boxing. They weren't afraid of ripping the cord or having the cord get in the way.
The Cord-Free without the sleeve, as intended.
The Cord-Free with the sleeve.
In other games like Metroid Prime 3: Corruption and Resident Evil 4, we found a higher satisfaction from playing games because the cord wasn't dangling around. It kept players focused on the game instead of the cord, which makes a big difference in the experience. The same applied to us.
To answer our own question, yes, the Nyko Cord-Free is a solid piece of hardware that does exactly as is claimed and more. It doesn't have the looks, but it has the functionality and has so far proven to be better for gamers. We also found that the added weight on the nunchuk and the base on the bottom was also beneficial, but once again for those with slippery hands it may not be too safe to shoot around. We haven't heard any reports of nunchuks going through TV's, so the Cord-Free is good to go.

An excellent piece of hardware that does nearly everything right.
