Spent a year or so with this keyboard now and its faults finally came up and annoyed me enough to get a new keyboard. The layout is nice and it's cheap and it works, but its price does show through in some aspects.
For one, it has a pretty bad "multiple keypress" problem, where key presses stop registering if you're holding too many keys at once. This can be a problem in games when you're often holding down movement keys.
Another is that some keys will start to "stick" over time and typing will begin to feel like it takes a lot more effort. The Ctrl and Delete keys in particular. It just becomes annoying to type with.
