Second Chance Logitech MX Vertical Ergonomic Mouse

What a SUPER mouse!
Your forearm is much more relaxed on your desk.
Speed can be set with 1 button, so it can be used by multiple users without having to dive deep into settings.
Connecting is really nice.
Via USB, via (Cool)Bluetooth, or the normal wireless stick that is included.
Battery lasts LONG, and charges quickly via the included cable.

I could go on and on about how this mouse at home and at work makes everyone's eyes and jealous, but then I spend more time with the keyboard than with the mouse, and I don't like it.

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

Working with the mouse for long days gave me pain in my wrist and muscles in my hands. Engrossed in vertical mice and chosen for its specific shape, accuracy and 'look and feel'. Very satisfied and the arguments mentioned have been very positive. It takes some getting used to this position, but after 2 days it is quite normal. A much more natural attitude, recommended!
