Preface: I am an MMO & FPS gamer, software engineer and business manager that has used every iteration of the Razer Naga and many MMO/productivity mice from other competitors. I am upgrading directly from a Razer Naga V1 Pro.Thumb Grid: Feels about the same as the Razer Naga V1 Pro. No complaints.Left & Right Buttons: Slightly snappier than my Naga V1 Pro, with a clean binary click; all on/all off as it should be. My V1 has a little give when you start pressing the buttons before actuating, feeling almost like a three-stage clicking mechanism. I am pretty sure this was a defect of my V1 Pro, so the fact the V2 doesn't have this is an improvement.Middle Wheel (Press): The current mouse scroll setting has a large impact on the stability of the middle mouse click. Smooth scroll and lesser tensions can make it feel a bit wiggly.Middle Wheel (Scroll): The meat & potatoes of the new mouse for my use case. It is extremely hit or miss and is underbaked in both development and support. While it is great to customize the feel of the scroll wheel, the software significantly limits the capability by only offering one slot for Custom settings.The setup for Tension & Degree of Rotation takes some time to get used to, but it should not take more than 30 minutes to dial in an "ideal" setting. I put ideal in quotes as no setting -- Standard, Ultra-fine, Smooth scroll, Custom, etc -- are what I would consider great.My largest complaint with the scroll is the disconnect between the scroll tension 'notches' and the actual output. While slowly scrolling, occasionally you'll feel the bump on the wheel, but no scroll action is sent to the computer. I have tested and confirmed this issue on three separate machines, using Custom and Standard/Ultra-fine wheel stages. I believe this may be a physical limitation due to the way the new scroll wheel is constructed to allow for such high customization. I much prefer another brands scroll-wheel in their productivity focused mice.30K Sensor: No use case where it presented itself as an advantage. The mouse has precise tracking as previous generations did.Battery Life: Too soon to tell; will update this review down the road.Software: Other than the scroll wheel settings above, Synapse still has a long way to go. Please add the ability to have device battery statuses (percentages) displayed in the taskbar. It would be great if I could assign a battery level color to the main Razer logo on the top of the mouse as well.Weight: Absolutely chonky. There is no universe where I would feel comfortable using this mouse for anything other than MMO's and office work. It can become tiring over long stretches of activity, which does not bode well for a mouse catering to the MMO audience, and also sports multiple side plate options for genres where it is sub-optimal in performance.Charging: I purchased a used 'Like-New' charging puck off of Amazon Warehouse and am using a pre-existing Quick Charge 3.0 Qi wireless pad. Thankfully they work great, so you can avoid the ridiculous price of the official offerings.Price: $179 at the time of this review is unmerited. The performance is on a similar level to the V1 Pro with some new annoyances and for most users, I would recommend the wired Razer Naga X or wireless Hyperspeed variants.
