It took some time to figure out what really was causing the problem, but it came down to this: The motor spins that little cam from one position (where it doesn't press the lever) to another (where it does press the lever). When the lever is pressed it disengages with the wheel, freeing it to spin easily.Ībove is a slow motion playback of what actually happens when the mode shift is activated. In the photo above you can see the lever that, when relaxed, puts pressure on the inside of the wheel creating the ratcheting action. It's a really interesting mechanism they've come up with to do the mode shift. With the screws out the top half easily pops off. Opening this thing up requires a Torx T5 driver ( try this if you don't have one) for the two exposed screws and a phillips driver for four screws hidden under the large plastic feet/pads. Seems like a common problem, but I couldn't find any solutions. It was loose, as if it was stuck between ratcheting and free-spinning modes and it no longer seemed to be able to switch modes at all. On the fifth day of use the scroll wheel started feeling strange. It was weird the first day or so, but I quickly began to love it.

This makes scrolling through long documents really easy. It's called SmartShift and it works like this: Normally the scroll wheel has the clicky/ratcheting feel that most mice have but if you flick the wheel quickly the ratcheting disengages and the wheel spins freely, automatically reengaging when the wheel is stopped. I even like the configuration software, "Logitech Options", which is saying a lot because normally peripheral software is terrible (looking at you, Razer.) and I do my best to avoid installing it.īut my favorite feature is something I didn't expect.

I'm a fan of the aesthetic too – the bronze and black color scheme looks sophisticated (as opposed to how edgy many of the gaming mice look). The construction feels solid and it has a nice weight to it. Here's the MX Master – a wireless, rechargeable mouse that can connect to either an included USB dongle or via Bluetooth. But it's the feature I found most interesting – the mode shifting scroll wheel.īut before we get into that, lets have a look at the device overall. It's actually only one feature that stopped working. I've had the Logitech MX Master mouse for 1 week and I already believe it's one of the best mice since the esteemed MX518.
