Review on Logitech MX Master 3 Advanced Wireless Mouse for Mac - Space Grey | Ultrafast Scrolling | Any Surface Compatibility | Ergonomic Design | 4000 DPI | Customizable | USB-C, Bluetooth, USB | Apple Mac by Matt Nichols

I was very excited about this product. This is such a cool looking mouse that pairs with my MX Keys for Mac keyboard, features Flow technology, is very smooth and customizable. But there are two big things that make this experience terrible for me. The biggest problem is the sensitivity of the right mouse button! A click is registered each time you place your finger on the button. Every time I just held the mouse in my hand, it registered as a right-click. I couldn't use the mouse because every few seconds the right click menu appeared and I had to click on it. At first I tried to take my finger off the button but this force when lifting the finger caused a lot of pain due to the unnatural force required! I then tried changing my grip so my middle finger wasn't on the button and my other finger was on the side of the mouse, but that was even more awkward due to the position of my hand and it was still consistently registering erroneous clicks when I switched to a right click. some! I ended up having to resort to slipping a piece of folded business card under the right button [see fig a photo]. Now the mouse works PERFECTLY! I can comfortably rest my middle finger on a button when using a mouse, and right-clicking requires active pressure (much like left-clicking) when I actually want to click! This is how the mouse should ALWAYS work, not just when a sheet of paper is folded underneath! As if all that weren't enough, the mouse is also generally not very comfortable ergonomically. The back is significantly raised and so large that my palm rest behind it isn't big enough to support my wrist while holding the mouse. I used to have a base, low profile mouse and the palm rest was perfect for relaxing while using it. So I end up having to bend my wrist away from the pad to put my hand on the mouse. In fact, for the first time in my life, my wrist started to hurt when using a mouse! I like the idea of this mouse. I had a great time tweaking the setup. I loved the look. The scroll wheels are very high quality! Pairing and features are great! But these few flaws make it unusable. And especially at a price of $100, it's just totally unacceptable. Shouldn't be a problem if you're willing to pay that much!
