Almost perfect - especially as it is (unfortunately) the only one.
It was the first AZERTY+ keyboard (NF Z71-300).
It is still the only one.
I ordered three, two for the home PCs, one for the office PC.
I'm very pleased with it, really, as a developer and commentator who is easily verbose and attentive to spelling as well as spelling.
The only downside (of the standard, not the keyboard) is the layout of the _ (AltGr 8)... after two years of use, I still often get my fingers too crossed at this manipulation.
I've been using it for two years now, and it's still too much of a pain in the ass to use.
And I recommend to the users of this new product to advertise it everywhere!
