Build Quality

Overall build quality is very solid. When shaking the mouse, a slight rattle comes from the scroll wheel. When applying lateral pressure, no creaking or flexing of the shell can be observed. Activating the side buttons by squeezing the sides is impossible. Lastly, accidental clicks when slamming down the mouse do not occur.

Buttons

Main buttons on the Naga V2 Hyperspeed are good to very good. Both pre and post-travel are moderate, but button response is sharp and snappy nonetheless, and the buttons are very easy to spam. Button stiffness is low. Though described as second-generation Razer mechanical switches, these are in fact modified Kailh GM 4.0 (60 M).


Side buttons are good. Pre-travel is low across the board, but all buttons can be pressed in a decent bit past actuation. Button response is pleasing all the same. The pressure point is mostly even across the entirety of these, with some exceptions. An array of tactile switches from TTC (black plunger) is used for these.

Next to the left main button are two buttons for cycling up and down through the set CPI steps, which work just fine. Two seemingly unbranded tactile switches (likely from TTC) are used for these. At the top of the mouse is a single button which switches between tactile and free-spin scroll wheel operation. The slider at the bottom switches between 2.4 GHz mode, Bluetooth, and the off-state, and works just fine.

Scroll Wheel

The scroll wheel is very good. Noise levels are elevated, but tactility is very good, resulting in very controlled scrolling. Alternatively, the scroll wheel can be set to free-spinning, which removes all tactility and allows for rapid scrolling. An optical encoder is used. Actuating the middle (scroll wheel) click requires medium force. A switch from TTC (black plunger) is used for this one.

The scroll wheel can also be tilted to the left and right, giving access to two additional button functions. A set of tactile switches from TTC (black plunger) is used for these.

Surface

The Naga V2 Hyperspeed has a roughened matte surface all over. Grip is fine, and it doesn't attract fingerprints, dirt, or the likes too easily, is easy to clean, and there are no signs of wear left after doing so. All in all, excellent materials.

Disassembly

Disassembling the Naga V2 Hyperspeed is fairly easy. First, all skates except for the sensor ring need to be removed. Four Torx T6 screws are found beneath, which need to be unscrewed. The top and bottom shell are easily separated now. When putting the mouse back together, best results are achieved by inserting the side panels first.

The internal design isn't particularly complex. The side buttons sit on their own PCB screwed into the left side panel and connected to the main PCB through a ribbon connector. A separate PCB holding the additional side buttons next to the left main button slots into the main PCB. Everything else sits on the very large and fairly thin main PCB. Five screws are used to affix the main PCB to the bottom shell. The MCU is a Nordic nRF52840, whose datasheet can be found here. Production date for the main PCB is the 42nd week of 2022.


As for the soldering and general quality of the PCBs, I'm unable to find any noteworthy flaws.
