My old review was as follows: I can not recommend this keyboard actually, since it makes significant problems with the spacebar. Even now, I use rather an external keyboard, since I am totally dissatisfied with this. To leave a space, you have to MND. 2 times vigorously (and loudly) hit the space bar and even that does not guarantee that a space will be set. With a flow of writing that has nothing more to do. Would not it be the spacebar, it would not so bad ... but that is now times primarily used. 30 Euro is something not worth ... ______________ Now my new: I have written to the dealer and explained my situation. Within a short time I was contacted by this and I was given the opportunity to get the money back or a new keyboard (without returning the old). Apparently, it amounted to a lack of keyboard from the production, so no fundamental mistake of the dealer. On the contrary, I have very commendable to be quick and friendly respond! This is true customer service. The new keyboard is working properly. The flow of writing is great. All keys can be used easily and react the first time. All in all (now) a super product!
