Review on Logitech G903 LIGHTSPEED Wireless Gaming Mouse with Hero 25K Sensor, PowerPlay Compatibility, 140+ Hour Rechargeable Battery, Lightsync RGB, and 25,600 DPI - Ambidextrous Design at 107G+10G Optional Weight by Michal Adach ᠌

So this review will be a comparison. I chose between G903, G604, G502 for a very long time, and none of them completely fulfilled all the requirements. I needed the most complete replacement for the G700s, but unfortunately Logitech threw its most loyal customers. The closest in terms of ergonomics was the G604 mouse, I almost ordered it, when it suddenly turned out that it does not have a charging port, and after 8 years of using this function, it is difficult to refuse it, in addition, it allows you to switch between two computers, in One can plug the wire into another USB receiver. Well, in addition, instead of a USB receiver with its own channel, for some reason they decided to use bluetooth in this mouse, which is an incredibly buggy technology even in 2022. I had to discard this mouse, which is a pity. In a difficult choice between 903 and 502, . market knocked me down, which ticked the 903rd in the "horizontal scrolling" field, I decided that the 502nd had no buttons when the wheel shifted to the side. What is the problem with the buttons? On the 700th there are 4 of them under the thumb and they have a convenient “hook” shape, you can easily feel where the finger is relative to the buttons, and with a slight movement, like when playing the guitar, lightly hook the button and the trigger has already worked. In everyday life, I had "Copy, Paste, Cut, Undo" commands bound on them for programming, just perfect! In games, you just had to assign the necessary triggers there, and now the mouse turns into a gamepad. In the G903, the buttons under the thumb require full pushing, the finger easily slips off them, and it is practically impossible to use the other two buttons on the back side, if the little finger can feel one more, then you can simply forget about the second. I will try to return the mouse and probably take the G502. Logtech is a big minus, for not being able to create a worthy replacement for the G700s, perhaps you should reconsider your preferences and look at what competitors are producing :(
