the Quickfire XT is IMO even better than the QFR. the legends changed slightly, the weight and build of the thing is amazing. The feet are much more wider than the QFR and stick to the desk an amazingly amount better than the QFR.
only negatives I have about it are
- pad printed carps ( more of a personal preference )
- LED's are way too bright. epsc in a dark room
- Full size USB plug, i'd still rather have a micro usb under the case and centered, but the full size one isn't terrible.
but that it can be had as little as $10 more than a QFR and comes in red, blue, green, and brown switches is awesome. and if you know the right people you can even get a hand on some white and clear switched prototype models.
