Very portable and extremely light. The keys are light, and they are not much smaller than in a notebook. Closes with magnets at the ends. Requires a few days to get used to the new ergonomics, but it is comfortable to the wrists. The battery arrived with charge 75% and continues to indicate 75% after a day of moderate use, it will certainly last days longer than the battery of the tablet. Has a quick answer. Negative points: 1-the keys do not register clicks if they are pressed only in the corners, you need to get used to pressing them further to the center or use the self-correct. 2-does not seem to be compatible with indication of battery percentage in iOS widgets, and I imagine that neither on Android. 3-it is a little boring to switch between devices, having to disconnect from one, and in the other, forget about the keyboard and pair again. I do not think it is preclusive except for those who have to frantically switch devices or want functionalities to copy on one device to paste on another.
