I've had it for two years, nice feel and shape, that's about it. The scroll wheel broke in the first year and the buttons have been overlapping since day one, making it difficult to play competitive slash games (Mordhau, Chivalry). So overall, it's pretty much useless despite its beauty.

At first, I was also hesitant because of the negative reviews I read about this particular product. The left button started acting up quite early (less than a year) and now the scroll wheel has become unbearable. If I had paid more attention, I definitely would have bought something else!!!

At first, everything was fine. After 5 months, without much use, the left button sometimes needs to be pressed twice for it to "register" once.

Let me also confirm, like the majority of those who reviewed the mouse, that it is unexpectedly PERFECT! I've had it for about 2 months and I've really enjoyed it!

Very good mouse, silent, fits in the hand, goes into sleep mode without needing to turn off the switch underneath every time (because I simply find it tiring), I switch from the PC to the TV with a click that is underneath the mouse, perfect! Connection with its connector or Bluetooth, these are great advantages for me and not just with one type of connection... generally, I have no complaints... time will tell, of course... just one thing, the side buttons cannot be customized, they are back & forward, personally, I would prefer them to be copy & paste.

Silent. A fitting application for the hand (personally, I prefer simpler shapes to hold it as I want and to keep the center of my palm free). Quite good accuracy but it’s not wired. Nice scrolling with the wheel, the issue is that as the hand fits on the mouse, because it has a somewhat short length, the position is not ideal when you need to press it... you have to move your hand further back. I am attaching photos in relation to the B110 Silent (equally quiet, here the problem is the hard wheel during scrolling...)

It is silent, with a nice feel to the keys, nice scroll wheel movement, very helpful that it has a USB dongle and connects to two Bluetooth devices with the push of a button to switch between the three modes, it has very good range, used in a presentation in an event hall as a presenter but... at first, its shape psychologically affected me. I felt it was so crooked and upside down as if it had taken a chassis. I was holding it expecting to keep it straight, like a regular mouse, and it adjusted to my hand to the left. I have not used an ergonomic mouse in the past and I don't know if this is something common for this category, but due to its price and its otherwise very good quality, I made an effort not to throw it into the woods and gradually got used to it.

Gift with laptop from Kotsovolos. I didn't expect it to be this good. Quality, quiet, durable, and fast! I will get a second one for my desktop!

Nice and very useful mouse at a very good price. Its connectivity to two devices is very useful.

It has fallen many times and once on marble from a considerable height, but it still works. As for issues with the "click," sometimes the plastic needs to be straightened out and it works normally, for 20-25 euros it is very good.

I have it for a few months, comfortable in the hand, lightweight, quiet, and good response in Bluetooth connection with the press of a button. It has not presented any problems despite falling a few times.

Durable.. good build quality.. Bluetooth.. energy-saving, after a long period of inactivity it goes into standby mode and activates with a click. Fast and user-friendly. Malfunction of the left button within a short period of time. Difficulties with the response of the single click. I am monitoring the wear and tear in order to address the seller within the warranty period.
