PERIMICE-804 Bluetooth Vertical Mouse, Bluetooth Connection for Windows and Android System, Works Without USB Receiver, Black

Great quality. Buttons are firms and mouse are comfortable to hold. Great value compared to more premium brand like Logitech but similar in terms of build-quality. Highly recommended.

Excellent for wrist and working daily for work.

It is a comfortable mouse to use. The left button doesn't always select what I am clicking on, but it may be that I am not used to this type of mouse. It is great if you have carpal tunnel. It allows your hand to sit naturally and relaxed.

Not so much a life saver, but definitely a wrist saver. I've had a job sitting in front of a computer for almost 10 years. A few years ago I switched jobs and the new desk was causing me to have a lot of pain in my wrist which was early carpal tunnel symptoms. I've been using this mouse for a week and it has alleviated all wrist pain for me. Before the switch to this mouse, my wrist would hurt within an hour, it now feels comfortable to use a mouse again. It seems very well built and is of better quality than I was expecting. It was very easy for me to get used to using too. The only thing that caught me off guard was that if it goes into sleep mode due to lack of activity, you have to press one of the buttons to wake it up again. If you are experiencing wrist pain, I highly recommend you try this mouse. EDIT* Jan 19, 2016. Its almost been a year since I've purchased this mouse. I use it every day at work. So far, I've only gone through one set of batteries. However the scroll wheel is now acting up. When I scroll down, the page will scroll up. This happens consistent enough to be an inconvenience. I'll be buying a different brand of ergonomic mouse soon. EDIT Feb 2, 2016. I contacted Perixx through email immediately after writing edited review. I filled out a form, emailed it back and they promptly sent me a replacement. It was not much of a hassle at all. Props to Perrix. Hopefully this mouse will last longer. EDIT* January 31, 2017 The scroll wheel is acting up on the replacement mouse. I'm not sure if I will bother contacting Perrix again. It seems to be consistent that the scroll wheel starts acting up after a year of use. I'll be buying a different brand soon.

im left handed and only use this type of mouse, as an HSE practitioner i see diferent type of injuries related to hand position that end in hand fatigue, with this type of mouse my hand is relaxed and i love the feel of it , bought my first just to try it and now i only use this type, have different brands all bluetooth. try it and judge your self.

Funciona bien Buen agarre

Bought this hoping to replace my current ergonomic mouse. It is now a spare backup, just in case something goes wrong and I need something until I were to get a replacement. It is way too light, the USB receiver does not fit snug into the retaining hole on the bottom for storage, it doesn't even fit flush up to the bottom of the mouse. As far as ergonomics go, it kept my hand upright, however it is very thin and requires you to use your thumb to hold it tight into your hand, which eventually causes cramping in the thumb/heal of my hand. Also, not having any kind of DPI settings on the mouse is a draw back. Normally for as inexpensive as this is, that wouldn't bother me, but when you can get much more comfortable mice that have this ability, at the same price point or lower, I feel like that is a huge drawback.

Most importantly - this vertical mouse is a great fit for me and has entirely eliminated my carpal tunnel pain! I have been using this mouse just over 1 year now. For most of that time I have been managing software developement projects and often spend 10-16 hours a day at my computer. This Perixx 804 Bluetooth mouse (https://amzn.to/45xA44B) has been a 100% reliable and dependable companion. I highly recommend this one. BUT... all of the vertical mice on the market are shaped and angled slightly differently. Before selecting this one, I tried 5 or 6 others from various brands that for one reason or another, did not fit my hand and working position as well as this one does. I strongly suggest you try several of these vertical mice to find the one that fits your hand and usage the best. Even within the same brand, or across brands with mice that look nearly identical, the small differences from one to another make a big difference in long term comfort and usability. Take your time to find the right one for your hand. Your body will thank you.

رهيب الماوس ومريح لليد لأنه يحاكي الوضع الطبيعي للكف والرسغ والساعد ويمنع التواء الأوتار وألتهابها اثناء ساعات العمل الطويلة

after I bought it for only three months.

Been using this "ergonomic" mouse for years now once you get used to the different position ( becuase of repetitive strain) you will never go back to a normal mouse

Súper súper recomendable. Te acostumbras muy rápido a la forma y tu muñeca lo agradece, ya se me quitó el dolor de muñeca. Excelente compra.

マウス操作が楽です。
