Look, I've had it for 6 years, it went through a tough quarantine, with daily use and absolutely nothing happened to it. Only in the last year did it have some glitches, sometimes it wouldn't respond. But I highly recommend it. I'm even thinking of buying it again

I have had the mouse for about 6 months and I use it both for gaming and for everyday use. In games like CS:GO 2, R6, CoD, LoL, and Fortnite it performs quite well and is fast. However, due to its small size, it is not particularly comfortable for me. It features a 2.4GHz connection with its own USB stick, Bluetooth, and a USB cable, so it is fully equipped with features. Nevertheless, for the price of 50 euros, I don't think it's worth it; it would be a better purchase if it cost around 30-40 euros.

Very nice mouse, with the only issue that occurred being the double click after 3 years of use. For its price (30€) I won't complain, I will order the same one. If it happens again within the warranty period, it will be replaced by Corsair support.

It didn't last long. The worst. For anyone who doesn't want to waste their money, there are two options. Razer Viper V2 PRO or Logitech G Pro Wireless.

One of the worst mice I have purchased. The buttons are very sensitive and it looks quite cheap.

What double-click?? It still clicks even 8 times with one click!! The company's update did nothing. Money wasted really. I can't use it.

1 year of use without any problems whatsoever, not even double click. Good response either with cable or wireless.

One of its very positive aspects is the shape, which is particularly convenient.

It's not a top-class mouse, but it's worth its money.

The mouse was fine at first. After 6 months, the left click works with difficulty and the right click is pressed twice instead of once on its own. I do not recommend this brand.

And I return 2 years later to write about this product! Okay, I don't know how it's possible for it not to work and for so many people to have issues, the mouse is FLAWLESS, its responsiveness hasn't changed at all!

I don't understand why half of the reviews are so bad. At first, I was hesitant to buy it, but being a user of the wired version of the same model, I decided to give it a try because I wanted something wireless, and so far it's been great in every aspect! Yes, it does make some noise, but in this category, that's what you expect and it's minimal! All of this after 1 month of use. If anything comes up in the future, I will write again.

I was satisfied for a few months. I treated it with care and love. Slowly it started to double click when I pressed it once until it almost always did. Also, after I changed the mouse, I discovered that the battery in this one runs out excessively quickly. It needs to be charged every few days compared to the Logitech one that I haven't charged the battery for more than two months that I have it. Beware, I will not buy this brand of mouse again.

Good and comfortable gaming mouse, the battery lasts up to 3 days with all RGB turned off, which is not good compared to my old mx master 2s that lasted for months with daily use on a single charge. Its biggest drawback is the corsair software. Some basic macros are not saved multiple times, the different profiles depending on the program/game running never worked correctly for me, and there is a significant bug since January (still not fixed) that causes double clicks instead of single clicks multiple times.

Update: After a clean install of the software, it lost the USB transmitter and I had to pair it again (fortunately, it is easy to do from the application), and now the mouse registers double clicks every time on certain specific windows.

I must warn potential buyers and tell them to stay away from this extravagant, with thousands of LED settings, garbage. What good are the settings, Corsair, when the mouse lags 50 centimeters away from the receiver? Unless you want it for Home Entertainment (you know, the couch 3 meters away from the media player PC), then there are much cheaper options available. Get a wired one and do your job like humans, instead of struggling with the fantasy garbage of companies.

I had the basic harpoon, in which the left click broke after a year unfortunately, outside of warranty, so I bought the same mouse again in wireless. After about 9 months of using the harpoon wireless, when I press the left click once, it clicks twice on its own. There is likely an issue with the switches of these specific mice. Other than that, it has a very good battery life and is very comfortable. I would recommend it as a mouse, but I believe there are more value-for-money options available.

I use it for work and a little bit of gaming. It is very comfortable in my hand and so far it works perfectly. A big plus is that it can be connected to charge directly without needing anything else.

Update 15/11/2020 - It continues to work normally with charging every 3 - 4 days.

Update 13/01/2021 - Occasionally, it does a double click in a spot that can be annoying throughout the day. The receiver is less than half a meter away.

The most value for money in its category.
After a lot of searching for a good and quality mouse (being a Logitech owner), I came to the conclusion to choose this one...
Initially, I haven't found anything bad and if there is, it will be edited.

Positives:
- Price
- Weight
- Responsiveness
- Plug and play during charging without interruption
- RGB lighting on the logo
- Battery
