I just received this keyboard today and I say it's a very good keyboard for it's price. It feels nice to type on but my backspace sounds a bit off compare to my other keys, it's not a big issue though. The lights are fixed so you can't adjust it, you can only chose what mode to use. Also, not sure if there's a mistake in the description or I got the wrong product but the key switches are Gateron, not Kailh. Since I like Gateron switches it wasn't a big deal at all. Would buy it again if I need an inexpensive blue switch keyboard.
