I sit every day between six and eight hours before the PC and had since about four months mild discomfort: general tension in the back and slight pain on the outside of the right thumb. High time to look around times for an ergonomic mouse and keyboard. I then decided to use the Wireless Comfort Desktop 5000 and am very satisfied. The slight slope is ideal for me as I do not work in the 10-finger system, ie not so well can cope with the high curvature of the classic ergonomic keyboard. The new keyboard I now sit automatically healthier and my wrists are noticeably relieved. The clear button functions make my work on the PC and let me work faster. The operation of the keys is pleasantly quiet, only the spacebar is a little louder. In the mouse, my pleasant Habtik noticed, especially on the sides. Surely there is a reason why the top has a different coating. Otherwise, would also be nice if they would have the same material and above. The form is perfect and the hand is very comfortable and ergonomically on the mouse. Conclusion: I would recommend the Wireless Comfort Desktop 5000 Tell A fully Microsoft. After a short adjustment period, I do not want to miss the keyboard and mouse. Discharge for the wrists and the neck and shoulder area is priceless!
