Missing a key to débalage

Package arrived in perfect condition. Unwrapped keyboard, it lacks the key (alt gr). Incidentally, I also discovered an average manufacturing. Lack of quality in the finish of the product such as screen buttons. It was windy me CHERRY brand. This first purchase disappoints me somewhat. Back to Amazon for immediate exchange.

Arriving replacement keyboard: All keys are present this time. I install it and try it. Comfort and use are similar to a good laptop keyboard. By cons, side silence, it is discussed. Most large buttons (clears, input, control, space, alt gr enter) leave a spring noise such as 1st prize ordinary keyboard. I confirm the average finish that does not inspire great confidence in time ...
Thirty euros for a simple wireless keyboard is much nowadays. This is the budget of a good wireless keyboard with mouse. So I expected much better.
Conclusion: I nachèterai more product CHERRY brand.

Meanwhile, thank Amazon for its efficiency and speed of processing.
