Interesting because the n52te is the best model yet for key response and feel...have an original n50, n52 and now n52te. I don't use it to move but it fires my spells just fine. I use the button above the pad as a temporary green shift to fire more spells and do many non-combat stuff like mount up and accept trades, invites, etc. The thumb button below the directional pad never worked right on my original n52's (had 2 of them thinking the first one was bad, but nope).

The one complaint I have about the n52te is the lack of a 4th uncolored layer like the original models. I had to put my X-keys pro aside for a bit since it's unergonomic (my left hand was hurting from using it so much) and have been using the n52te for a couple of weeks now and it's much more comfortable. I'll definitely be still using the X-keys pro at some point (alongside the n52te) when I start instancing more with mixed classes.
