Bests & Worsts Reviews from Amazon

This is a pretty expensive keyboard. I will say this, I like the quality, weight and feel of the keyboard. It has the ability to connect with a bluetooth connection, or with the included dongle. Great! With the cool LED lighting that comes along with it I thought this would be a perfect solution to having two PCs, one for work, one for gaming. I could easily use the wireless peripherals with both machines and not have to deal with a ton of wires. Can you imagine then my disappointment when I discovered that this expensive keyboard is lacking in the ability to simply program the keys to light up as a single color without running their software in the background? Well, it's a pretty big disappointment. I am using this keyboard to connect to multiple PCs and it just doesn't work well for that purpose because my work PC can't control the keyboard lighting! WHY?!?! This seems like such a simple feature to have in the keyboard. UPDATE!!: Ok, so I am amending my initial review of this keyboard to 4 stars. Why? Well, I discovered that this keyboard actually does have some tricks up it's sleeve. If you don't want to use the included software you have to use some key combos on the board and you can change the default effects that show when the software isn't running. You can press the number key multiple times to cycle through the available colors. Fn+CTRL+1 = lighting off Fn+CTRL+2 Static Color Fn+CTRL+3 Breathing LEDs Fn+CTRL+4 Color Cycle Fn+CTRL+5 Rainbow Wave (Press 5 again to reverse direction) Fn+CTR:+6 Not sure what it's called but the keys light when you press and fade. Fn+CTRL+7 Random keys light up across the board. Important info to have if you are like me and running multiple PCs and can't/don't want to use the synapse software.
