MX Master

I’m upgrading from a SteelSeries WoW Cataclysm Mouse, which was a wired MMO mouse, since I don't play games or even MMO’s anymore and it was starting to become faulty i thought i’d upgrade, and i figured i’d upgrade to a wireless mouse since the technology has come a long way in the past few years. (Included photo next to my old mouse)And oh boy it has come a very long way, i remember my first wireless mouse was a dell one, and i remember playing games on it was so bad, you could see and feel the input lag, and that mouse honestly put me off wireless peripherals forever, but I heard a lot of good stuff about the technology logitech uses in their mouses so it bought back some hope for me, and this mouse has solidified that hope in concrete because it's amazing and you honestly can’t even tell it's wireless.I got this one over the other wireless mice they have because it is more feature rich and looks more comfortable in the hand, it has a scroll wheel on the side, which to be honest would be useless for most people, but for me it helps because i draw in photoshop and it's good for scrolling sideways across the canvas, the only downside to the scroll wheel on the side is that the back and forward side buttons are in a very awkward position and difficult to press ,and they are small and close together so you find yourself hitting either the wrong one or both, now this doesn’t bother me too much as I don't use them often, but I imagine it's something you can very easily get used too.Like i said earlier, you can’t even tell it's a wireless mouse, it's so responsive and there is no lag at all, not that the human eye can see anyway, if you recorded it and put it in super slow mo then you could probably see, but if you want to play FPS games you totally can and would have no disadvantage against people playing with wired mouse.Also, I should mention the scroll wheel has two modes, and i find it hard to explain but I will try my best, one mode is like a traditional mouse wheel scroll where you keep feeling tactile bumps as you’re scrolling, and the other removes the feedback and makes it so you can spin the wheel like you’re spinning a prize wheel, it goes insanely fast, i don’t see an application where this would be useful, but I did see someone say it would be good for scrolling long word documents but you can just slick on the side where you want to be so in my opinion that wouldn’t be a very good use case, but hey ho you might find that super useful, i just don’tOverall this is just a great wireless mouse and I really recommend it, it's got a great price, the build quality is amazing, the battery life is amazing, ive been using it for 5 days now (About 8 hours a day) and it's still on full bars! And as i mentioned earlier the only downside I can see if the side buttons being small and awkward.10/10 Highly Recommended.If you found this review informative or helpful please mark it as such, I'd really appreciate it.

I've had this month for nearly two years and use it every day at work, so this is definitely a long term review of the product rather than some reviewers who review a product as soon as they've opened the box.First up, it's up to you whether you like the styling but personally I love the bronze secondary colour of the mouse which makes it stand out compared to most mouses which use silver or grey. It's got a nice rubbery feel so feels nice in the hand and size-wise, it is a large mouse so it's very much a palm grip. To be honest, you don't even 'grip' it as such, more rest your hand on it. It's got your usual left and right mouse buttons, a vertical scroll wheel between them then next to the thumb rest is a horizontal thumb wheel, two buttons (back/forward) and the thumb rest actually clicks down as a 'gesture' button. Behind the vertical mouse wheel button is a small button which switches between ratchet and smooth scrolling.Connectivity is via the small USB 'unifying' receiver which is the same as many other Logitech mice, so if you have one already you can reuse that or use them on different computers if you plan to travel with the mouse. Alternatively you can use Bluetooth but it needs to be a specific version (I think 4?); my old laptop wouldn't connect to it but my current laptop does. You can also use a micro USB cable which is also how you charge the mouse. One nice feature of the mouse, which you may not find useful, is that you can connect the mouse to 3 different machines and switch between them via a small button on the bottom of the mouse. Pairing is as simple as holding this button down until the led indicator flashes, then it is in pairing mode.The mouse can be programmed using the Logitech Options software. The vertical mouse wheel can automatically switch between ratchet and smooth scroll mode if scrolling fast enough and the sensitivity of switch can be set in Options. Other buttons such as the back and forwards buttons, horizontal scroll and the gesture button (clicking it, or holding it down and moving the mouse in different directions) can all be customised to do different things, from basic tasks to keyboard commands. Not only this, but they can be set up to be global settings and then have specific settings for individual applications, so for example you could have the horizontal scroll button to scroll through tabs in Chrome. A lot of these things can be a bit niche but the ability to program the mouse so much is nice to have - I have a program where the horizontal scroll by default zoomed in and out, so I was able to turn it off for that specific program.The mouse has a built-in battery and as I mentioned before, charges via a micro-usb cable. The battery lasts a long time, I work 9-5 five days a week and I would estimate it needs charging once a month, if not less frequently. You get an alert on the screen to say when the battery is 'critical' (5%). I can get another day out of it until it dies and needs recharging. Charging takes very little time (an hour perhaps) and you can continue to use it while it's charging.I wanted this mouse because I wanted an ergonomic, wireless mouse and I've loved the look of the previous Logitech mouse which this is the successor of but never bought one. This mouse really has been a positive change to my working environment - I am a software developer so the automatic smooth scroll feature can help to fly through thousands of lines of code quickly. The programmability is excellent so I can get it to do certain tasks which save small amounts of time. Overall, it doesn't feel like it hinders my workflow, which a lot of cheaper mice can do. There's no poor battery life for a wireless mouse, messing about repairing because it's decided it doesn't want to connect for some reason and it barely feels like you're holding anything.
