I brought one of these back in January, where I had an issue with the touch panel, whereby every now and again, it would mute the systems sound, and then the touch panel would just stop working. This then started happening more frequently, so I decided to return it.
I emailed amazon on a Sunday, and recieved an email back from them within about 30 minutes! They sent a replacement out the next day, to recieve it on tuesday, and had DHL to come and collect the old one. Second to none customer service! Thank you Amazon!
Anyway, to the product itself. Firstly, as others have said, it is big, so before buying, make sure you have enough room on your desk.
The keyboard has shortcut keys to various things on ethier side of the keyboard, which I find pretty useful. However, there is no software included that will change what these keys do, but you can change the programs it opens through setting different things as default, such as if you want the music key to open a particular music application, set that as your default music application.
The touch panel allows you to change the backlight, volume, mute, play/pause and fast forward/rewind, and if you install the drivers from saiteks website, the volume part will light up and dim dependent on the systems volume. However, I have found that this touch panel can be a little annoying to use, as it doesn't respond all that well when you try to change the volume
The Keys themselves are ok, however, they aren't anything amazing to type with, but you should get used to them.
The keyboard is relatively comfortable to type on, the wrist rest is fine.
There is a headphone and microphone 3.5mm jacks on the top right side, which can come in useful. You don't have to use them for headphones/microphones though, you could say, have two audio outs from it, or 2 microphones or whatever. It comes with gold plated connecters and what seems to be fairly good connecters, so I doubt you'd be loosing too much sound quality through using it.
The backlight is very useful when typing in a dark room, and looks pretty cool too, I usually have it on red or blue, there is also 3 shades of purple/pink. You can alter the brightness, but I always just have it on full. I personally would have liked the brightest setting to be a little brighter, but that's just me. I have noticed that the Eclipse logo on my new one isn't actually lit up, I'm not really bothered though, but with the other faulty one, and this, it doesn't show much quality control, but maybe I'm just unlucky, as I have not read anyone elses reviews where they have had any problems with it whatsoever.
Pros:
Nice backlit keys, changable colour and brightness
Useful shortcut keys
Relatively nice to type on
Headphone/microphone ports
Cons:
First one faulty
Touch panel controls can be a bit unresponsive
Would have liked it to be a little brighter
Very expensive, at over £40
Overall, it is a nice keyboard, however, is worth the amount it's being sold for? I'll let you decide.
Thanks again to amazons awesome customer service!
