Owner and user of this mouse for two and a half years. Today it broke, and as I am looking for a new one, I decided to leave a review. It was purchased in April 2021 for a total of 25 euros.
Build quality: Perhaps the main characteristic of any product. I have no experience with other mice, but for its price, I find it decent. After a lot of use, the external plastic "peeled off" (I don't know how to describe it, the outer coating came off like a film). 4/5
Feel: Left-handed in everyday life, right-handed on the computer. Personally, I wasn't bothered by the feel of it. I don't grip it with my palm to judge such a grip, but in a typical finger grip, it didn't cause me any issues. 5/5
Buttons: Average. It will be analyzed further, they are not quiet. The scroll wheel has a strange texture, it makes noise when rotated and sometimes doesn't respond to movements. The main click buttons are noisy (53 dB according to measurement). I never needed the side buttons. The ball was personally useless to me, and the texture was strange. The lighting and sensitivity (DPI) buttons work properly. 2/5
Weight: It's a mouse. I don't know how much it weighs, but its weight didn't cause me any problems while dragging it. Personally, I would have liked it slightly heavier, but it was good as it was. 4.5/5
Functionality: In everyday use, it does what it was designed for. In games, I only used low sensitivities (usually 1000 DPI), without any responsiveness issues. However, I am not an FPS gamer nor have I run targeting and reaction time software, so for this specific aspect, seek other opinions. 4/5
Software: Good, functional, user-friendly. I used it minimally to adjust the sensitivity (DPI), but it has many settings, with Macro programming capabilities. Demanding users will definitely find strengths and weaknesses, but for regular users, it is more than fine. 5/5
Noise: Oh, if only it were quieter. As mentioned before, the scroll wheel makes a lot of noise (the measurement software recorded 64 dB, between the sound of a conversation and a vacuum cleaner in normal operation). The main buttons are also noisy. Generally, if you are looking for a quiet mouse, look elsewhere or be prepared for modifications inside the mouse. 1.5/5
Other aspects: Personally, I would prefer it to be a modular mouse (detachable) for ease of cleaning and modifications, but for this price, you can remove most of the shell. I would like the ability to completely turn off the lighting for nighttime use, the LED off function is at least satisfactory.
Lighting: You never buy something for its aesthetics, so it's the last thing. It's nice (???). Personally, I had the RGB lighting show turned off because it bothered me, but if you're interested, it has plenty of settings to play with. I wasn't interested/5

Conclusion: For a 25 euro mouse that lasted me 2+ years, I am satisfied. However, in 2024, I cannot recommend it when there are more advanced mice with better capabilities at a lower price. Decent product, a worthy member of technological history.
For those who have read this far, congratulations. You have the ability to maintain your attention for more than 8 seconds. Put it on your resume because it will soon be considered a masterpiece (maybe it already is). As the days are festive, happy 2024, without any breakages and other problems.

Owner of the mouse for less than a year. From the beginning, very satisfied with my purchase as even from opening the box, you can tell that they paid special attention to make it not look "cheap".

As for the mouse now. Whether it is comfortable in the hand is a matter of personal preference, so I won't comment on it much. I, with a larger palm, found it quite comfortable, while my girlfriend, with a smaller palm, did not find it comfortable at all. The shape seems ergonomic, but the size is not suitable for everyone.

In gaming situations, it performs very well, BUT. It may be common sense for most people, but for me, it was my first "good" mouse, so I learned many things now. One of them is that you have to adjust it yourself through the Zeroground program, which is free. I didn't know this as I was used to €10 mice that didn't have many options, resulting in some suffering in many games.

If you buy it, immediately download the program from their website. Through it, you can adjust everything related to the mouse. DPI, macros, RGB, etc., among other things.

As for the construction now. It has not been tested in adverse conditions like being hit, as those are for 5-year-olds. However, it has fallen from the desk a few times during transportation, etc., and the mouse didn't notice anything. It seems sturdy as it has weight and nothing on it creaks or looks like it's about to break.

I haven't done any detailed tests because firstly, I don't know how, and secondly, I'm not interested. In real conditions, the differences would be negligible with mice in this price range.

If you are looking for a quality mouse that will last with a little care from a company with good customer service, I recommend it.

I bought the mouse 2 months ago and have been using it daily since then. The mice I had before this were the Razer Naga and the Logitech G502 Hero, so I will compare it to those (although it's a bit unfair because they are much more expensive).

Starting with the negatives, the thing that has given me the most difficulty and forces me to replace it is that it is very "hard" to use. Its clicks require more force than other mice, resulting in my fingers getting tired after continuous use. Even the middle click requires a lot of force, while the scroll wheel movement is very light, causing me to try to press the middle click but instead move the scroll wheel. Even dragging it on my mousepad felt like it required more force than usual, resulting in a loss of accuracy.

And to mention the positives, the build quality is very good, especially considering its price. The accompanying software for customization is excellent and user-friendly, allowing you to adjust DPI, LED colors, patterns, sensitivity, and much more.

Of course, all of the above are personal opinions and depend on individual preferences.

I have had this product for about 2 years now. I didn't want to write a review immediately when I got it, but rather after using it extensively to see how it performs.

On Windows 10, this mouse works directly with your graphics card drivers. So, when you change your set DPI levels, you can do it with the DPI button located in the center of the mouse.

Then, you will see a nice graphic on your screen displaying the DPI level. It's a wonderful effect, very modern.

You can adjust the DPI levels with precision, although not absolute precision. It's not as precise as my old Logitech mouse (G400) which broke quickly and never satisfied me as a product. The bar increases every 250-300 DPI approximately. I am satisfied with this system. I play with low DPI settings, 750 and 1000.

It would perhaps be better if the DPI levels had a smaller distance between them. However, I think this design is decent for most gamers.

If you want absolute precision in DPI adjustment, you will have to dig deeper into your pocket, unfortunately.

Zeroground is a reputable, serious Greek company that manufactures digital technology products. It was founded in 1998. I have purchased many products from this company. Their goods are made in the great country called China.

They are all very affordable, of good quality, and highly durable. The primary right and left buttons of the KENNYO mouse have a lifespan of 10 million clicks! Impressive, don't you think? Overall, the KENNYO mouse has 9 buttons.

The switches are called Huano. The optical sensor, PIXART 3212, is highly accurate. The maximum resolution reaches 7200 DPI. The mouse is recommended for right-handed users.

On the side of the mouse, there are three buttons. Two are simple, and one is a red multi-function button.

The customization and adjustment capabilities of the KENNYO through its lightweight and beautiful application are incredible! You can find the application at https://www.zero-ground.com/kennyo-20. Scroll down to the bottom of the page and click on the "Download" letters.

You can change everything, literally. From lighting with 10 different styles to a full palette of colors.

You even have the ability to do Macro editing, although I have no idea what that is! But it's great that such an option exists for advanced users.

The KENNYO has an internal memory of 16 KB. It also has a switch on the bottom and in the application to easily switch between 2 different parameter profiles. Mode 1 and Mode 2.

At the same time, you can save the profiles you have created in a lightweight .bkm file format and easily restore them in case you do a clean Windows installation and fear losing them. I recently formatted my computer, so I used this very useful feature of the KENNYO.

Its highly durable cable has a length of 1.7m. The material is braided, sturdy cord. Indestructible.

The USB connector is gold-plated for the best possible connection with your computer. The weight of the KENNYO is moderate at 143 grams.

There is no weight adjustment option. Just know that you will get used to the weight of a new mouse in a short time.

However, I believe that moderate weight in mice is ideal for gaming. I don't like overly heavy mice at all.

The KENNYO is a large mouse. Its precise dimensions are: 126X75X40 millimeters.

I am tall and have big hands, so I bought this specific bulky mouse. On its left side, it has a groove to rest your thick, large finger. Very convenient.

It is a comfortable and ergonomic mouse. However, it is only suitable for right-handed people. Pay attention to this.

Its packaging, made of cardboard, is a proper reproduction considering the money you will spend at the cashier. The front part opens to clearly see the mouse under its hard plastic cover.

Additionally, the cardboard, which acts as a door, has magnets on it for quick and easy opening and closing.

Truly, the packaging of the KENNYO is a proper reproduction! Just by looking at its amazing aesthetics and beautiful colors, you will want to buy it!

However, be careful not to hit it out of frustration when playing, as it will break quickly. I had some issues with the right and left buttons because I used to hit it out of anger.

But then, it started working fine again. Its surface is rubberized and non-slip, so it won't easily slip from your hand like other mice.

In conclusion, the Zeroground Kennyo MS - 3600 G gaming mouse is a worthy and reliable choice for gaming. It is made by a significant, smart, emerging Greek company, Zeroground.

Their products are getting better with each passing year, and believe me, I have bought many different items from this brand.

Equip yourself, aim well, and enjoy your new little mouse!
