I set my keyboard a career and realize in this Logitech model, it is just as good as those of Microsoft. The so-called "learning curve" which due to the differently arranged keys deleted at the Logitech product and the work with real pleasure. The pressure point of the keys I find perfect. The fact that the intended's batteries hold for 3 years, I can not Nocht beruteilen but a small light is present at the battery condition display once they are empty.
There is in my view a small flaw. The keypad keys are noisier and do not seem to have the same technology as those with letters. Since I use the numeric keypad much I feel this is slightly annoying. Yet I saw here no reason to assign a star less.
The significance of the keyboard I classify as high. The workmanship is very good for my understanding. The value for money is so very good. The location of the special keys, I find very practical. Only the Zoom button I would have - desired in the middle below the space bar but that's surely just a matter of getting used to - as in the Microsoft keyboard.
I am very pleased with the keyboard and would recommend everyone who wants to write the purchase.
