This keyboard is a true wonder. Typing is more comfortable. It was delivered very quickly. He arrived loaded to 100% (bravo!). The only slight concern is the feet that are used to tilt. They are obviously quite fragile. So not to put in the hands of users a little "cram." Its sensitivity to light for charging is exceptional because the electric lighting in the room is sufficient to recharge. Do not forget to download the application to verify the quality of the load and the lighting on the logigtech site.
