Logitech MX Vertical Ergonomic Mouse

Pure as a mouse, this is the quality you can expect from Logitech: precise, good build quality, works on every surface, material feels pleasant. Clicking is a bit tricky at first as you have to counterbalance it with your thumb, then you sometimes get the effect of moving the mouse a little while you click. As far as ergonomics are concerned, I can say the following. It takes some getting used to not to overextend your hand, but to simply put it in line with your arm. That said, the stride is much smaller than a trackball. You immediately feel that the movement comes much more from the elbow and less from the wrist. I wouldn't dare say that there is no more load on the wrist, but it is quite different. I use this at work and at home I use a classic mouse, so overloading is certainly not an issue. The reason I bought this mouse (sore wrist) ended up having nothing to do with overload, so I can't testify that this mouse really solves that, although it certainly feels different from a classic mouse. further:

• I had to charge the battery for the first time after 2 months, you can continue working via USB cable.
• connection via bluetooth works perfectly
• Most mice are too small for me and offer too little support. This one does that quite well, but it's still not the ideal solution for people with large hands.
• the switch button to switch between sensitivities is quite nice, but after a while you can just do everything on the most sensitive setting. You can adjust the sensitivity of the two modes with some software that comes with the mouse.
• easier to punch given the height
• I really miss side-ways scrolling with this mouse
