This review is for the Redragon K552 mechanical gaming keyboard with red LED backlight. The buttons stick. Redragon has no support, so don't bring that crap back. Not even a year. I have purchased a number of Redragon products and all but two have worked flawlessly. Both were quickly replaced. I bought about 5 different mice and 4 keyboards. Why am I giving this 1 star? Because if you go to their website, that product doesn't exist. No manuals or software downloads. I can't stand manufacturers who stop supporting their products after a year. Does it really take up so much space on your site that you can't have a single page for that product? Obviously not, they're just being lazy and want people to think that this model isn't supported. If there is too much support for older models on the site, I just switch to another brand that does. The mouse is not 10 years old.
