Ordered after my keyboard (Logitech also) who passed away. Less customizable keys than others (6 keys with three modes, so 18 in all) but it's already a lot. The backlight is class and not obtrusive. To make a word processor, it is just perfect, the keys "carry weight" without being too harsh. For games, I tested and it is also very good. The software for setting the keys is so easy to use and can do lots of things.
In short, I recommend it to those who want a high quality keyboard without wanting to put 100 to just have a small screen gadget and more!
