A bug? Comments posted here now (21-2-15 to 13h) does not concern the "Trust Isla Keyboard French" but a backlit keyboard I looked just now. I think it was the "Trust eLight LED Illuminated Keyboard Keyboard USB French": exactly the same comments.
I do not know what its customers really think, but the "Trust Isla Keyboard French" does not deserve to be awarded the criticisms on another ;-)
