Pros: LCD Screen, Customizable Backlight, Custom Apps
Cons: Broken Drivers
I have a Razer Nostromo and a Razer Naga and the only reason I want to upgrade this keyboard is for consistency and how dim the back lit keys are in comparison to Razer products. Lately as well, I've had issues with the drivers and always have to look up work arounds for each problem which does solve it but I shouldn't have to. On startup, each application that the keyboard utilizes will launch and initially slow Windows start up and I'm assuming it become less of an issue with an SSD.
It definitely has its quirks but I love this thing. The only way I plan on upgrading this keyboard would be if I could get another LCD screen that will read the same apps I've come a custom to for the past few years. Easy to recommend to people who constantly monitor framerate and temps but don't like onscreen displays.
