Because to me about my old keyboard juice has gone, I have been looking for a new and decided on this one because I never had a problem with Microsoft keyboards. The external looks chic and the keyboard is not loud when writing. On the curved shape have to get used briefly, but after that it's easier to write with it as with other versions. There are some useful additional buttons available. The keyboard is not overloaded on keys. Overall, a favorable product, but this is still competitive with more expensive keyboards. From me a strong buy recommendation.
