really great - as long as it works

I was supposed to give 5 points of the keyboard, because she writes great, has a nice stop feeling is nice and flat and - as you might think - is the solar technology still a little green.
And there is then already the hook.

I in 2011 decided to send my now 20 year old keyboard in pension and zuzulegen a chic, new home and workplace keyboard. almost 2 years performed the K750 their work pleasantly and without mosquitoes who also installed solar app to query the state of charge and the lighting conditions showed in a bright room always mediocre 95-100% battery charge. One fine day it was all over then. I turned on the keyboard and they refused to serve. Completely. Without a sign.
A call to Logitech's Service and 3 days later I had a new keyboard in hand. This worked until recently einwandlos, but it invites no longer the battery correctly. Replacement Battery (ML 2032 the battery version of the 2032 coin cell) did not help make the blazing light does not help, and the Support? Well, unfortunately I am to 3 months beyond the 3-year warranty and Logitech does here now no more substitutes.

I luckily still have my old keyboard (like I said, 20 years and still works) and my Logitech mouse by 2002. I will bring both now out of the cellar, wipe once and hopefully use again for 20 years. DAS is then environmentally friendly and sustainable.

My conclusion: A tool has to work, an expensive tool must also reliably and long. What good is a great look and feel, if I can use the keyboard only for a very limited period of time? Nothing. In addition, the environmental awareness of a solar keyboard remains fully on track if after a short time the whole thing moves into the trash - and that twice in a row. Therefore, there is only one star from me. Schade Logitech.
