Build Quality

Overall build quality is mostly solid. There is no rattle when shaking the mouse. When applying lateral pressure, major creaking and some flexing of the shell can be observed, to where the side buttons contract slightly. 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 VT3Pro Max are good. Pre-travel is moderate, whereas post-travel is low, resulting in a firm and snappy button response nonetheless. Despite being visually separated from the shell, button movement is fairly low even when provoked. Button stiffness is medium. A pair of Omron D2FC-F-K (60 M) (China) switches are used here.


Side buttons are very good. Both pre and post-travel are low, though feedback will have a different pitch when pressing the back button towards the rear. Actuation is satisfying nevertheless. The actuation point is even across the entirety of these. Button placement is good as actuation is possible very easily by rolling one's thumb across. A set of surface-mounted switches from Kailh (green plunger) are used for these.

At the top of the mouse is a button for cycling through the set CPI levels. Another surface-mounted switch from Kailh (green plunger) is used for this one. At the bottom of the mouse is a single button which cycles through the available polling rates. In addition, a simple on/off-slider is also found on the bottom, which works fine.

Scroll Wheel

The scroll wheel is decent. Noise levels are significant, and tactility is merely average, as the individual steps aren't particularly pronounced. The encoder comes from Kailh (GE 2.0) and has a height of 13 mm. The middle (scroll wheel) click requires high force for actuation. An elevated switch from Huano (green plunger) is used for this one.

Surface

The VT3Pro Max has a matte surface all over. Grip is fine, and it doesn't attract fingerprints or dirt too much. It is easy to clean, and there are no signs of wear left after doing so. All in all, excellent materials.

Disassembly

Disassembling the VT3Pro Max is easy. The screws are found beneath the front and rear skates. After removing those, four additional clips at the sides and front need to be dislodged, doing which may require wedging a credit card (or similar) in between. When separating top and bottom shell, make sure not the rip the cable connecting the two.

The internal design is very efficient. The very thin and compact main PCB holds the sensor, MCU, scroll wheel encoder, and scroll wheel switch. On top of the sensor, the battery sits on a sticky pad. A secondary PCB connected through a ribbon cable is screwed to the top shell. This PCB holds the top button switches, and two PCBs holding a main button switch each and connected through a 2-pin connector as well as the side-button PCB connected through another ribbon cable branch off. The side-button PCB is screwed to a plastic assembly, which in turn is screwed to the top shell. The MCU is a Realtek RTL8762GKH, whose datasheet can be found here. Production date for the main-button PCBs is the 28th week of 2024.


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