Razer Pro Click Mini, Logitech MX Anywhere 2, Rapoo MT550, Logitech MX Master
Among these mice, only the Razer Pro Click Mini is relatively new (released in 2021), while the rest are older products that have been discontinued, with not much improvement seen in their subsequent versions.
A common feature is that all of them support both a 2.4G receiver (paired with one receiver) and Bluetooth mode (switching among three devices).
The standout feature of the Razer Pro Click Mini is its “Infinite Scroll” wheel (referred to as hyper-fast scrolling by Logitech); it offers a nearly zero-damping scrolling experience, making it great for browsing long webpages and Excel sheets. I find it hard to go back to normal scrolling now. The left and right buttons are also quiet (though there’s still a slight sound, it’s quieter and more subdued than the typical mouse click). I use this mouse only when I’m in the same room as my wife or child to avoid disturbing them. It takes two AA batteries and the battery compartment can store the 2.4G receiver. With just one AA battery, it can function, and if you use an adapter for AA to AAA, you can achieve a working weight of 81 grams. However, the wheel scrolling switch can’t be set to activate by pressing the wheel, unlike Logitech, and the switch button is a lever instead of a press, making it less convenient. The Razer “Razer Synapse” software is much worse than Logitech’s; I don’t even bother installing it.
The Logitech MX Anywhere 2 is my favorite mouse. After the warranty expired, the microswitches started double-clicking (the quality control on this is abysmal). I found someone on a secondhand platform to replace the switches, and it’s been five years with no issues and it seems like they will last a while longer. Apart from not having a storage compartment for the receiver, the “Darkfield Laser Sensor” is practically incapable of working on glass surfaces. The tactile feel of the scroll wheel is better than that of the Razer. I will continue to use it for a long time, and I have no desire to switch to its subsequent iterations (this generation’s scroll wheel can also scroll horizontally). Logitech, you are always criticized for your software, which is indeed frustrating, but compared to Razer, it’s much better.
The Rapoo MT550 can also use a single AA battery, and its battery compartment can store the 2.4G receiver. However, it lacks the hyper-fast scrolling feature. The biggest issue for me is the poor tactile feel when scrolling; I find it unacceptable. The key travel for the left and right buttons is slightly shorter, resulting in a slightly unclear tactile feedback. The design and functions are still decent.
The Logitech MX Master, although I rarely use it since buying it, I haven’t considered selling it secondhand. The biggest problem is its weight; it’s incredibly heavy, weighing 150 grams in actual usage!!! I don’t feel like using it after picking it up. The side scroll wheel is hardly utilized and is prone to collecting dirt. The design of the side buttons prioritizes aesthetics over comfort. It’s quite challenging to press the thumb button effectively. The so-called ergonomic design feels more like a gimmick, or perhaps it’s tailored for larger hands. Using it leads to quick fatigue.
I’ve been eagerly awaiting a true ergonomic wireless Bluetooth mouse that genuinely fits the contours of the palm, ideally with an upward slant or at least a vertical palm position. Unfortunately, despite all these years, no manufacturer has developed such a product.
