I personally use the 3 Cherry eVolution STREAM XT Corded MultiMedia Keyboard G85-23100 - keyboard and have experienced so far no failure. This may probably be because I do not einhacke my letters, but something soulful operated.
I would buy the keyboard due to the flat design, the simple appearance and impeccable functionality (with the exception just mentioned in accordance with hard use) at any time or to recommend.
