Just got one of these (with blues) and have been using it for a few days now at work after leaving the venerable Chicony KB-5181 behind.
I like the feel and the click; it's lighter than the Chicony. I like a tilted keyboard, so I had to add a 1/4" thick bar under the red footbar to get it where I wanted it.
The main thing I don't like is the spacing between the main key set and the six [Ins-thru-PageDown] key set, and between those and the Number keys. The gap between them is narrower than the Chicony. I tend to hit those keys along the outer perimeter on their edge, so I keep tagging the Ins key when hitting the Backspace key, and the snagging the NumLock key when selecting the Page Up key. Other than that it's good for me. Still feels a little on the light side, but I'll get used to eventually.
Oh and they need to coil the wire instead of the back and forth setup which is for packaging of course. The thing took a set and is badly kinked.
