Below is the script for my video review on Youtube (under title: Logitech MX Vertical Mouse - 30 Days Going Vertical). I purchased this with my own money and this is an unbiased take. Thank you :)Vertical mice have been around for some time now, but this is the first one Logitech has ever created. Logitech is known for making very nice, high quality peripherals at an affordable price. Their MX line for lack of a better term is their flagship line and typically comes at a higher cost. But at that high cost you’re getting better features, a built-in battery, a unique/premium design and the overall craftsmanship is just better. And this mouse is no different.Overall the body of the mouse is composed from a plastic polymer which allows it to be equal parts durable and light as it comes in at around 135 grams. The portion of the mouse where your hand rests on and interfaces with has this nice texturized, rubber coating. This texturized surface allows for improved grip and allows the overall end user experience to be that much more comfortable.The MX vertical mouse has 6 buttons in total, 4 of which are customizable via Logitechs downloadable application.Along the right edge is standard left and right buttons and in between is the scroll wheel. The scroll wheel is depressible, customizable and has that same rubber coating as the rest of the mouse. It is buttery smooth, has a subtle click and feels so nice when turning it. Along the left edge there is two more customizable buttons. These are just above where your thumb lies and are easy to reach, even if you have smaller hands. Along the top edge just adjacent Logitech’s branding is our last customizable button. This is also easily within reach and comes setup as a DPI adjuster out of the box. This button allows you to toggle between 2 different DPI settings, both of which can be adjusted by holding down the button and moving the mouse.The DPI range of this mouse is extremely impressive. It can cover as low as 400 dots per inch or a maximum of 4000 dots per inch. This is helpful for a few reasons: firstly the higher the DPI you can achieve the more area you can cover when moving your mouse. This is convenient when you have a larger monitor such as an ultrawide or when using a 4k monitor as you can cover more pixels with less movement. Higher DPI is usually emulated via settings within the software but this results in less smooth movement which is important for professional work or while gaming.And less movement feeds into the main ideology of this mouse. Higher dpi allows for less movement which is less strain on your wrist, resulting in a more comfortable experience. This is the main reason why this mouse exists: to minimize strain on your wrist and increase the overall comfort. It does this by allowing for a higher DPI range but mainly by altering the way your hand rests on the mouse.The average mouse orients your hand parallel with the surface. In order to achieve this position your forearem twists and is forced into a pronated position. This causes stress on a major muscle in your wrist, the pronator quadratus. This muscle (along with the pronator teres) is responsible for turning your wrist inward and maintaining this pronated position. Not only is your wrist stressed but in order to maintain this position your elbow is forced to flare away from your body causing a secondary strain on your deltoid, which in turn causes a tertiary strain on your upper back near your scapula.In order to relieve this strain, Logitech has re-oriented the angle at which your hand rests on the mouse. Rather than being parallel with the surface, the mx vertical mouse is oriented at a 57-degree angle. This is a more natural position for your wrist to be in and helps reduce strain greatly. Not only does this reduce the strain in your wrist, it also helps keep your elbow tucked closer to your body, allowing your deltoid to relax, and further preventing it from causing strain on your upper back.In terms of connecting the mouse you have 3 options: you can connect wirelessly via Bluetooth or with this included usb dongle. And lastly you can hard wire in with the included USB type-C cable. The usb type c port also allows for charging. The mouse has a 240mAh battery and Logitech claims you can get 4 months of battery life on a single charge and I actually think this is accurate. Over the 35 days I have owned this mouse, I have used it 2-6 hours on a given day and have put roughly 80 hours of use on my first charge. And according to logitech’s desktop application my battery is still near full. Only time will tell if it actually survives 3 more months without needing to reach for the cable but as of now it’s excellent!The MX vertical mouse is also capable of connecting up to 3 devices as it has an easy-switch selector on the bottom. This is nice if you’re wanting to use this across multiple computers and it switches effortlessly whether you’re on a pc or mac.Overall this mouse is great. It attempts to provide a more comfortable, ergonomic experience and reduce strain in your wrist and I have to be honest I was skeptical at whether or not this would even achieve that goal. I mean I’ve never had any wrist issues before would I actually benefit from this? The answer is a resounding yes. After using this mouse for just over a month I can comfortably say this mouse will provide you with a more comfortable experience and it will make you aware that you are causing stress to your wrist. Just transitioning from the mx vertical mouse to my keyboard, I can feel a drastic difference in my wrist. It immediately becomes strained when typing and relief is found when I go back to using the mouse.If you have any wrist or arthritic issues definitely give this mouse a look, it may just provide the relief you need. I know I won’t be going away from mine anytime soon.
