We all know that the mouse and keyboard have something called the rate of return (of course, not the economic rate of return of big A shares), simply put, that is, the mouse gives a signal to the computer, and the computer and the mouse say I received, and the number of call reports within one second between the two is called the rate of return or report rate (report rate), which is actually similar to the definition of hertz (hz), so the unit of return is hertz. For example, if you call me and I respond again, one back and forth in one second, is the rate of return 2.
Specialized 4K return receiver, Rapoo.
Generally speaking, the higher the rate of return, the stronger the performance of the mouse, the easier it is to use, and the more enjoyable it is to use. The average gaming mouse, it is good to be able to achieve a 1000hz return rate, not to mention the daily office, and playing games is not a problem. As for the rate of return of 4k Hz, it is generally necessary to have a special receiver. For example, I used such a plug-in receiver last year, and the mouse in my hand can also be upgraded from 1k to 4k return.
However, the mouse I shared with you today is a bit unexpected, at the time node in 2024, it can actually use a USB wireless receiver without plugging, and it can achieve a 4K return rate. This is Rapoo's VT9 Air. I have a real feeling and experience of using it, and I would like to share it with you.
Let's talk about its appearance and appearance first, in fact, many people will pay attention to it. The VT9 Air features a translucent case, which has the feel of a previous Discovery Edition phone, and looks very cool. However, the manufacturer sent me a white-purple version, which is pure white as a whole, with some purple accents. I was a little disappointed at first, but then I liked this white mouse style more and more, I wonder if everyone is the same as me?
On the left and right sides of the appearance, there are two ridge lines extending backwards, which makes the whole mouse look more three-dimensional and full of streamlining. On the left side are two function keys, which can be customized. At the top is the scroll wheel and the DPI setting button downward. There is no button on the right, but there is a dotted place with an English logo on it.
At the bottom is the storage compartment of the USB receiver and the on/off key, and there is a pink custom key. Further on is the Type C interface, which can be charged and data transferred. The overall shape is a relatively simple style, and it is symmetrical, and it can be used for both left and right handers.
The feel of holding it,It belongs to a class of mice that is on the small side。 Therefore, the grip is okay, there is a feeling of grasping with one hand, and the palm of the hand is relatively not so full, so it is more suitable for small and medium-sized palms. If you have a large hand and a tall body, you can choose some other styles to try. Another point of use, is very light, the whole mouse (of course, including the non-removable lithium battery), the total weight is about 59, very light, it feels like an egg.
When it comes to performance, it has to be tested. Open my dedicated mouse test software (now this kind of software is quite difficult to find, if you have a good use, please comment and recommend one, thank you very much), the most critical test data is its return rate. Because this software is relatively old, it can only measure a return rate of 1200 at most. At the time of testing, the 1200 was running full!
Moreover, the movement trajectory of the mouse is very smooth, without a point, there is really no lag or disconnection at all, and it is quite easy to use. I feel that its performance is a little inconsistent with its appearance, there is a feeling of King Kong Barbie, small and cute, but full of powerful power, which may be a portrayal of Rapoo VT9 AIR mouse.
The return rate just now is USB wireless mode, if it is wired mode (with the A2C port cable of distribution), the lowest is 125 Hz, and the highest can even reach 8000 that is, 8KHz. At this point, everyone understands, right? In fact, many people prefer to use a wired mouse to play games, because it will be more stable and the performance will be more powerful. Of course, today in 2024, unlike before, even in wireless mode, as long as there is a strong receiver, the transmission rate and stability can be well guaranteed.
Why is there such a powerful performance as 4K return? Let's take a look at some of the hardware inside, including the sensor is PixArt's custom 3398 optical engine, and the chip is Realtek's low-power chip. Another important parameter is that its DPI can be as low as 50, and the maximum can reach 26000, so DPI can participate, and it can be used on a screen with 8K resolution. The tracking speed can reach 650 ips and the acceleration can be up to 50 g. From the hardware point of view, it looks like a very powerful hexagonal warrior.
In addition, there is another advantage of using it, I think I am quite satisfied, that is, the battery life can reach up to 180 hours, and if you use it normally, you don't need to charge it for one or two months.
I believe that everyone must also have a Rapoo mouse in their hands, or have used it before, so for Rapoo's VT9 Air, it costs more than 200 yuan, but the performance has the level of a thousand-yuan mouse. Perhaps, this is one of the products of the human world - the mouse, the state of evolution in 2024. What do you think?
Thank you for reading, and I wish you a happy life!
