Looks like a pretty decent keyboard however the lack of a numpad and macro keys would be a bit of a gripe for me.
It is really aesthetically pleasing piece of work. Custom mechanical switches are sometimes good and sometimes bad, I myself still prefer the Cherry MX range.
I myself I am currently using a Gamdias Hermes Elite however it is only available in a few countries.
What I can recommend would be:
Logitech G410 ATLAS Pretty similar to keyboard mentioned in question (However a bit more expensive in my country)
But on the whole the RedDragon looks like a pretty solid buy that will impress.
Hope i could help
