The keys look really, really good in the rendering. Possibly some of the nicest key designs ever. The shape of the keys and the grainy texture feel really good to my fingers - they paired up nicely with the Plum87 keyboard I bought last year.
The colours are a bit off: in particular the orange is more vibrant than one would expect in comparison to pictures as well as the other more subdues hues of the coloured keys.
My biggest complaint is with the lettering; it is not very good. The lettering is bit too fat, yet he :; key and the >. key have (in my opinion) unacceptable tiny dots. Also there is some variation of line-thikness, the < arrow is a bit fatter than the other arrow keys and not all F keys are centred properly. Also some keys like my T is not aligned properly.
I got no response from the sellers when I asked if some of the obviously badly printed keys could be replaced.
All in all - the set not worth the premium price I paid for them.
