I dare say this may be the BEST gaming mouse on the market, PERIOD. I think the main thing that held Razer back was that their shapes have always been hit or miss. Or you have a mouse that has a great shape but doesn't have great specs or weight. For the first time they have a mouse that has a 10/10 shape, at a 10/10 weight, with 10/10 specs. It is simply phenomenal and I'm in love. Unless if you really don't like right handed ergo mice I'm not sure how you couldn't like this.
First, it has the best specs out of any other mouse on the market (with the exception of the Razer Viper V2 Pro). As the Focus Pro sensor is so incredibly precise and my aim has never been better. No joke I broke every single record I had on AimLabs my first go with this guy.
Second, the wireless is phenominal. I've had zero issues with it. If you look into the tech behind it they use two 1,000 Hz signals at the same time (not 2,000 Hz) to swap to whichever has the best signal to give you the best stability and response time. You can also add a 4,000 Hz dongle to make the wireless even better (granted you burn through battery A LOT faster).
Third, the battery life is great. They report 90 hours with constant motion. I've used it non-stop since I got it and only had to charge it once. Charge time is a bit long at about 3ish hours.
Fourth, the Gen 3 optical switches are the best feeling Razer clicks I've tried to date (and I've tried ALL of their mice). Switching from the single shell design to this being split makes a massive difference. Add that to immunity to double clicks, no debounce time, and 90 million click life and you've got yourself a mouse that will last a long time and give you the lowest latency.
Fifth, I'm in love with the new shape. The old shape just felt a bit too wide and large for me where this updated shape is perfect for my 19x11 cm hand. It is ergonomic where my natural wrist angle is just right. But also has the correct shape that I can easily manipulate the mouse itself all over my hand for those ultra precise shots.
Sixth, the PTFE glide wonderfully. With my palm never actually touching the desk this is even more apparent. I really don't even notice any drag.
Seventh, they updated the scroll wheel. I'm not as big of a fan of this. As it is extremely light with dedicated steps. It also sticks up a bit more than the previous version. But is incredibly responsive as well. So it works phenomenally. I just like a bit more stiffness personally.
Eight, weight. I took a long time to get here but this is what makes the absolute biggest difference. Going from I think 89 grams to 63 grams is game changing. I've wanted a premium lightweight ergo for years and it has finally arrived and is better than I imagined. I'm easily able to use this all day long (with aggressive tracking and flicks) with no fatigue what so ever and keep maximum accuracy the whole time. It is also perfectly balanced.
Ninth, the coating. I think they nailed the coating. But think this will be the hit or miss with most people. I found if my hands are super dry it can be a bit slick. But has very mild bumpiness that helps with grip. If you're hands are slightly moist it sticks to it really well. Where if they are really damp it is still sticky but less so (but better than when it is completely dry). Probably the best coating I've seen from Razer yet. I prefer it over the GPX.
The only cons I can think of is that they took away features (charging dock, RGB, a place to store the dongle, bluetooth, rubber sides) in exchange for weight, feel, balance, etc. To me these are "upgrades" to others they will be "downgrades". Also, the $150 price point is steep. However, I'd argue 100% worth it. As I've bought other mice at the same price tier that aren't anywhere near as good. When you buy the best of the best (and by some margin in this case) you will always be in the premium price tier and the way supply chains and the economy is everything costs more.
