The pressure point, the design and processing are excellent in my opinion. I have owned no better keyboard with respect to the writing feeling.
Unfortunately disappointed the keyboard through a rough design flaw: The solar cells charge the battery permanently on, which is known to destroy a battery for some time, and use the battery not only as "emergency reserve". For me it is now after 4 months of the case. The keyboard can only load to over 80% if it is a whole day under a desk lamp. For this purpose it discharges by around 35-45% in the daily use. Admittedly I'm sitting but also a lot of computers, it is thus used at a high frequency. Resolve allows the whole by the battery is replaced, which is very simple and the problem probably fixes temporarily (3-6 months). A battery of the type costs without shipping around. 5
The problem seems really occur not only with me, as can be seen from the Logitech forum, and will not be further considered by Logitech except through the battery replacement under warranty. The cost of using this service is probably out of the question. In my opinion, a recall or a refund is due. I for one do not have to send in the nerves the keyboard every 6 months at Logitech.
Personally, I recommend the purchase from and definitely would do instead to an alternative keyboard with a similar keyboard-Feeling like a Cherry keyboard attentive. Once again, I would not buy this keyboard, because the problems described above makes the keyboard for me unusable. If this were only an "exceptional problem", which would quickly fix would, the keyboard get 5/5 points, so I can not forgive only 1/5 and am very disappointed.
