Kensington Ergonomic Vertical Wireless Mouse (K75575WW), Grey/Black | Vertical grip reduces wrist strain, wireless connection, comfortable all-day use

Good quality, good grip on the hand, smooth - the speed button works great. Using it with Macbook pro M1. Just ordered a second one for my office !

It was so easy to get used to it, it helped me a lot with my wrist pain from using the traditional mouse shape

Mouse works well. If you want to plug/unplug it often, I don't recommend. I takes a lot of effort, sometimes with tools to eject usb connector from the mouse.

Just don't loose the dongle

I had one before same design but Germany brand. Unfortunately I did not find the same brand again. This one was similar in design but not in accuracy and performance. I am using it for engineering CAD drafting drawings, it's suddenly scroll up or down which let me lose focus on work, some times suddenly left click not working. Now I can not return, Is there any warranty?

The scroll is broken and this my second mouse

Product is of very good quality, and the concept of vertical hand positioning itself did help to relief the stress from my wrist in specific and my arm in general.

Good for bigger hands

I ended up buying this mouse because A: I trust the brand and B: my clicking arm was killing me and I needed to try something different. I am in front of a computer for most of the day. As well, my hobbies include woodworking and music, both of which involve a lot of right hand manipulation. Over the years I've had periods where I would develop pain in my right arm from repetitive motion, but it would usually go away on it's own after a few days. Just before Christmas, it came on worse than it's ever been and didn't go away. I read that vertical mice were easier on the nerves in the arm because of the more natural position of the arm when using the mouse. It's true. I've been using this mouse for just under two weeks and the changes are dramatic. The mouse works great, doesn't require any special "getting used to", unlike a track ball, is a good price and is idiot proof to set up. I'd give this six stars if I could. I've never gone wrong with Logitech. One added note: I'm six foot, two with big hands and this mouse is comfortable. My wife is five foot two with little hands and it works great for her as well.

Good, feels easy to use. One cool option is that the mouse automatically turns off when not in use. If you are looking for vertical mouse in budget friendly option. Please go for it.

(English Text Below) كان أداء الفأرة في البداية رائعًا، لكن بعد نحو عشرة أشهر، صار الانزلاق الشاقولي (الرأسي) بالبكرة مُشكلًا فإذا أردت النزول إلى الأسفل نزل قليلًا ثم قفز إلى الأعلى، وكذلك في العكس. هذا مزعج جدًّا فأنت لا تتوقع ما سيحدث ولا تجد الفأرة تأخذك حيث تريد. المؤسف أن يحدث هذا بعد زمن قصير وبفأرة غالية كهذه. This has been wonderful at the beginning. However, after about 10 months, scrolling started going crazy, so if you scroll down it does so for a bit then jumps up, and vice versa. This is very annoying. I tried all troubleshooting tips I found but nothing worked. It seems to have gone bad permanently. This is too bad because you can't expect where you'll end up and you lose control. What makes it worse is that it is not a cheap mouse and it hasn't lasted one year.

Para cuando hago este comentario, ya a pasado más de 1 año. Funciona muy bien durante los primeros 6/8 meses, después de eso, comienza a fallar la rueda del mouse. Y para cuando cumplió el año, el botón izquierdo falló por completo. Lo abrí para repararlo, pero solo me duró la compostura otros 2 meses. Punto a favor: es bastante cómodo para manos grandes como las mías. Si quieres un mouse para uso común o de oficina, lo recomiendo. Pero si lo quieres para un uso duradero y/o profesional (diseño, edición, gaming) no es lo mejor.

I love this mouse. I love the design because it takes the pressure off the inside of my wrist and for the price I have use this 5 days a week for about 2 years with no issues. I’m going on my 3rd one of the same thing because after a few years the scrolling gets a little wonky so I just replace it with the same thing. Batteries last a while, I keep rechargeable batteries on hand for it. It’s not heavy, not hard to move
