Buttons, Scroll Wheel

Main buttons are pretty good on this mouse. They are mostly tactile and spammable, with a medium click tension, and don't seem to have any significant pre or post travel, although the left click has slightly more overall travel on my copy—only noticeable when I take a close look, it is not an issue during regular use. Switches are blue shell Huanos with a nominal life expectancy of 20 million clicks.


Scrolling is quite light. It doesn't have much resistance or tactility, but isn't overly loose either. It's definitely better for browsing and heavy scrolling than precision movements. There is pretty much no play inside a single notch, so the build quality is pristine here. The encoder is a green core TTC model.


The middle mouse button is quite stiff, and it generally doesn't feel good to actuate. This is mostly a matter of personal preference, and since it has such high tension, accidental clicks are virtually nonexistent. The switch is a red plunger Huano model.


Side buttons are rather generic, and they don't feel too nice to actuate, either. The rear buttons on both sides are extremely mushy with a lot of pre travel, while those on the front are a bit better. They operate with LXA elevated tactile switches.


The CPI and lighting changers, which can of course be remapped via the software, are great; they are nice and tactile, of medium resistance, and have no unnecessary travel. They use the same Huano switches as the scroll wheel button.


Lastly, there's a small tactile switch at the bottom of the mouse that changes the main button layout between the right-handed and left-handed modes.

I also made a video in order to demonstrate how the buttons sound:

Mouse Feet

The mouse feet are nothing special on the Impulse Pro, but they aren't the worst, either. They are of average friction and smoothness, and their contact edges could have been rounded better. As for replacements, the company includes a set in the package, which is a nice addition, especially at this price point.

Cable

The cable is the thing I dislike the most on this mouse. It's overly stiff, heavy, thick, and generates a lot of drag resistance. Using a mouse bungee or affixing it with some tape is highly recommended. It is 1.8 meters (5.9 ft) long, and the USB 2.0 connector is gold-plated.

Disassembling

Disassembling the Impulse Pro is really easy. All it takes is the removal of two standard Philips-head screws from beneath the two bottom mouse feet. Once done, you can simply slide the two main shell parts apart. You don't need to be overly careful either since the top shell doesn't feature any electronics at all.
