Lousy impression arrangement of cursor keys unfavorable

Was disappointed. Under the name Curve there are various versions. Have in the work the Curve 2000, which is worlds better than the advertised here Curve 3000th
Pro:
* Price
Cons:
* Stop spongy beat, often accidentally to adjacent keys, without one would feel right at finger
* Arrangement of cursor keys poor, blind practically impossible to use, because they are not surrounded by an area
I would not buy it again. Too bad that Microsoft sells as a scrap and dirty the name. Other keyboards of MS (eg Ergo 4000), however, are top class.
