My two main iFlyz gripes: 1) There's no way to easily adjust the tray-table clamp or lock it in place; and 2) the gooseneck arm that lets you position your device is too rigid and not quite strong enough to support the full weight of an iPhone or BlackBerry Bold in all possible arrangements.

For example, the only way to open and close the iFlyz tray-table clamp is by yanking and pulling on one end until it budges--which is easier said than done when it's clamped shut for travel because there's no good place to grab onto it. And you've got to squeeze it shut on your tray table when you want to employ it. The product would greatly benefit from some sort of handle or crank that lets you tighten and release the lock without having to grope and pull at its edges to get a grip.

iFlyz's gooseneck arm is bendable in most direction, which helps to comfortably position your devices for viewing, but it's not really strong enough to bear the full weight of the iPhone 3G with its arm extended upward in the 12 o'clock position. Since the product attaches to a tray-table that's typically going to be lower than your eye-level, it's almost always going to be titled upward. Since iFlyz isn't quite strong enough to bear the full weight of your smartphone while fully extended upward--your iPhone will keep drooping down--its overall value is greatly hindered.

While I had relative success with iFlyz and my iPhone 3G, the product just didn't get along with my BlackBerry Bold for one simple reason: The Bold has a rough, faux-leather back cover. The tiny iFlyz suction cup works fine on smooth surfaces like the rear side of the iPhone, but it couldn't quite get a solid grip on the Bold; the device would stay put for a few minutes and then simply drop from iFlyz into my lap.

Finally, at US$29.95, iFlyz is just too expensive, even if that price does include shipping. The company claims iFlyz is the only product of its kind that can be used while your seat tray is both open and closed. Regardless of whether or not that is true, there are plenty of alternative product that serve similar purposes. And most of them cost (much) less than iFlyz. Two examples: 's $15 ; and the $5.99 .
