I can highly recommend the must. I myself use the mouse now for over 3 years. I had never thought always tension in the neck and shoulders and have that may come from the mouse. So I just made an attempt. After about 10 days, the tensions were gone and have never since returned. Meanwhile, my daughter and my employee also has a. And what can I say: even the tensions are gone. The Wowpen Joy mouse promotes the natural position of the hand and therefore the muscles are not twisted in the forearm, so easily to anyone who has the same problems: buy an ergonomic mouse! I've also tried a different mouse, but returned after 10 days, since the scroll has hooked. The Wowpen Joy has been going on for years with no problems. One has to get used to it, however, that you have to raise your hand when you release the mouse and the keyboard to change. Initially, the amount of your mouse, the one stuck with the hand. But you get used to it and the disappearance of the tensions is the familiarization all value. Conclusion: Highly recommended !!!
