"Minor improvement from the n52"4.0 starson by rcolbert
Pros: Solid build quality - on board memory
Cons: Could use an additional top row of keys
Summary: In honesty, I respect the previous poster, however I have not encountered many of the problems that had been described.
I find the n52te to be quite stable, and have not had any issues with the fit or finish.
On a side note, I tend to keep things quite simple with the keypad, and don't typically use more than two layouts per game. One layout tends to be primary, and the second is typically accessed using a momentary shift. Frankly, I wouldn't be able to remember what key does what if I used four layouts in a game.
One major deficiency is the lack of another top row of buttons. The row above the QWERTY line in most shooters would be great as either a number row or function key row. Fortunately, the workaround is easy for me. I use a mouse with enough buttons that I can assign 1-8 to the mouse and have become very comfortable using the mouse for weapon switching. It's actually quite intuitive since the mouse itself controls aim and fire.
I'll then assign the large button above the d-pad as the momentary red-shift key, and then function keys F1-F9 to keys 2-4,7-9,and 12-14.
I typically have no use for the scroll wheel since the mouse has one as well. Finally, the d-pad itself is most useful as 'big-picture' keys like <enter>, or keystrokes assigned to map, scoreboard, etc.
I can say after several months of use I haven't had a moment of slippage at either the hand rest or base.
Could be better, but pretty good anyway.
