After a week of using the Razer Pro Click V2 Vertical Edition, I have to say that the first few days were all about getting used to it. The mouse was initially "skipping" and the biggest problem I had was with moving down and adjusting the DPI. After about two days, however, I started to get used to it and the controls improved significantly. At the beginning I felt a slight pain in my hand due to the change of load, but on the contrary, the wrist pain subsided, which I take as the main benefit. Without Razer Synapse software, the mouse is limited in its use - most advanced features and settings cannot be used without it. At the same time, I miss the ability to save RGB or macros directly to the mouse memory, so you lose settings when using on multiple devices or without Synapse. The RGB backlighting has minor flaws in my experience. After waking from sleep, the mouse glows white briefly before switching to the set mode. In some cases, I have also had the RGB not light up at all after some time. I miss the ability to charge via dock or stand, which I would appreciate at this price point. As for battery, at my settings (RGB 40%, brightness reduction to 50% in use, polling 1000 Hz, DPI 1400, sleep after 5 minutes) the battery dropped from 100% to 32% in 7 days, with about 24 hours of active use in total. Actual endurance may vary significantly depending on settings and usage style. Switching between wireless and wired mode requires the use of a button on the bottom, which is not entirely convenient. I solve this by charging the mouse with a cable and using it wirelessly at the same time. For work and casual gaming, the mouse is usable without major problems after getting used to it. I play more casual games (RPG), I haven't tested FPS. For larger hands, the mouse might be a little bigger, and if you lift it often, the extra weight might not be suitable. If someone is considering this mouse primarily for health reasons, it is good to consider that it is not a "miracle solution". While the vertical shape relieves one part of the hand (especially the wrist), it puts more strain on the other. As a result, it's more of an add-on than the main solution. The overall ergonomics - i.e. the correct desk height, quality chair, hand position and regular exercise - have a much greater impact. The mouse is the last step, not the first. I enjoyed the mouse and it's not bad, but due to the ailments, shortcomings and findings, I finally decided to return the mouse and wait to see if we move on in the future.
