I use this keyboard for 4 months now and so far can largely positive report. The keyboard has no tactile feedback of the keys, which I find very pleasant while gambling. Enclosed there are spare keys for WASD and arrow keys. However, this replacement keys feel to something cheap and bring no advantage anyway. Is meant nice, but not absolutely necessary.
A star deduction there is that the> button is in place on the keyboard (where the right Windows key is) but not working. (Works as a Windows key)
