[AT&T, Rogers HTC One X, Telstra One XL] QQNoob:
The Gametel controller is now available on Amazon.com. I got mine in the mail today. Here's a quick review.

It came with no battery charge, so I had to plug it in to test it out. I was using a USB cable plugged into my computer. At first it only showed a red light to indicate charging, but then a green light came on shortly afterward. This is supposed to indicate that it's on but not paired. I tried pairing with the device using the Gametel software from the market, but it would not work. Turns out you can't use the controller while it's plugged into a computer. As soon as I unplugged it it turned off, and when I turned it back on it paired fine. I tested it again while plugged in and it still wouldn't connect to the phone. No big deal, but it's a minor hassle. It might work fine when plugged into an outlet. It supposedly has a 9 hour battery life, so just keep it charged and this issue should never bother you.

Despite the One X's huge size it fits fine, even with a TPU case. The TPU case has the added benefit of keeping the controller arm from pressing the down volume button. The software has a feature to disable the volume keys because of this potential issue, but it's nice that I didn't need to use it. It says it can provide volume control using the device itself, but I'm not sure how that would work, since all the physical buttons are mapped to SNES buttons for my purposes. You could always slide the phone a little bit to the left and it wouldn't hit the volume key. The phone would be off center, but it wouldn't be too bad.

The controller acts as a virtual keyboard. As part of the software setup it installs an input method in your keyboard settings. As soon as you launch the software it prompts you to change to its input method, which is handy. Then you can launch your favorite emulator and map the keys is uses to the emulator's buttons.

I initially had problems with the default keys that the controller was emitting. I'm used to an SNES button layout, so I will call the buttons X (top), Y (left), B (bottom), A (right). For some crazy reason the A button was emitting the Android "Back" button by default. This was mappable in Snes9x EX, but pressing it still performed the "Back" action which prompted you to quit the game. The B button was emitting the "DPAD Center", which worked, but was an odd choice. It's even stranger because none of the preset key configs in the Gametel software's Advanced Settings have this setup. If this happens to anyone else, just load the Android Gamepad preset and it will work fine. However, it reverses X & Y and A & B from what I'm used to, so I made my own preset named SNES. That way when I configure Snes9x the purpose of the button matches up with the key being emitted.

As for the controller's buttons and D-pad, they are OK. The buttons are great, but the D-pad makes you move diagonally a little too easily. If anyone is familiar with the Xbox 360 D-pad, it's the same sort of problem, but not as bad. Maybe with more time I'll get used to the feel of exactly where to press to avoid moving diagonally. Part of the problem is the D-pad is circular instead of cross-shaped. It's hard for your thumb to feel exactly where the cardinal directions are. This isn't the entire problem, though, because the 360 controller has clearly raised cardinal directions and it still sucks really bad. Thankfully it's not nearly that bad with this D-pad. Pretty much anything is better than on-screen controls.
