I purchased this case because of the ability to use it as a stand in portrait or landscape mode. but after only 3 days, the turning ring broke apart. Useless to me now.

Good Keyboard, never owned a mechanical, I have owned plenty of other high end keyboards, Logitech G15,G19 Razer Etc. They all typically fail within 2 years and found that the Ryos Mouse was of good quality and their keyboard sure has not disappointed me as of yet. Thanks again Roccat!

We had rated it at about a four prior to today. The reason why we only would have given four stars is that they shipped it out without the requisite firmware. My computer guru( #3 son) had to update the firmware a couple of times, the last time last night. This morning, no Internet, just a buzzing router with no lights flashing! So, since we are just under the wire w/ Amazon, we're going to send it back and get a replacement, hopefully it will not behave the same way. There should have been no problems, but we did have 12 wireless devices running on it. That's why we got it, so it would handle our heavy wireless use. Will update with info on replacement...
