A very good keyboard, but that could be a reference if it had been better designed. The reasons for my half-contentment (or half discontent choice): Robust and comfortable keyboard, but sometimes the Bluetooth signal loss. No elastic or other system to maintain the closed keyboard. System Standby the defaulting iPad (if we do not close the cover to the millimeter, the iPad does not turn off) Very good battery life, but no protection for solar panels. With its experience and resources, Logitech could have done better.
