The controls are laid out nicely and are pretty much like the original Xbox controller. The normal functionality won?t require any learning curve. The buttons for the turbo function (Turbo and Clear) are located below and to the left of the left analog stick. This seems to be a good spot for them, as you?re not going to accidentally hit them while moving the left stick or D-pad.
The Back and Start buttons have a diagonal orientation and are located too closely together for my tastes, but once you get used to it, it?s not that big of a deal.
The lighting feature works independently of the controller, and is controlled by its own power switch, which is located beneath the Back and Start buttons. This is, again, well placed. I can?t see any way you?d accidentally flip this switch. For that matter, if you did, it wouldn?t have any great bearing on your gameplay.
There are rubber grips on the side of the i.Glow, which I personally find to be nice ? especially when playing for long periods of time. These grips help to keep the i.Glow securely in your hand, even when gaming gets intense and your palms start sweating.
I found the i.Glow to be comfortable even during long periods of play; it fits the hands well, the controls are easy to reach and seem to be oriented nicely, and the vibration feature has a nice feel to it.
