I took it to replace the sticky Razer Naga 2022, after a week of use I found how to clean the contacts on the clickers both on the Razer and on the A4tech X7 755 Conclusion - the old X7 is much nicer, the clickers are quieter, the buttons are pressed softer, it feels better in the hand (subjectively) PS After half a year of use, the hand got used to it, but in general everything remained as described above, if it weren’t for the design that fits perfectly into the Aerocool Mechatron BE case, it would return the old X7. The problem with the "freezing of the mouse" remains, sometimes you have to reconnect it to get rid of multiple clicks caused by the software part
