Build Quality

Here, you can see the relatively simple PCB of the mouse. The main mouse buttons next to the wheel as well as the wheel switch are visible in the top half. You can also see the small PCB switch used for the CPI cycle, just under the wheel.


Here's a look at the design of the top shell.


A visual annoyance is the light bleed through the side buttons. These are most likely designed in such a way to minimize weight by not including a plastic cover inside, which has them look very cheap for a $80 mouse.

Buttons

Here's a better look at the side button switches, the wheel encoder, and the wheel itself.

The main buttons feel very good: The separate button pieces allow for a crisp and light click, and the Omron switches offer good feedback. The side buttons feel weaker in comparison, especially the back button has pre-travel and suffers from a mushy feedback. You can also see that the connection for the side button's PCB seems to be done with hot glue. I don't think it is an issue, but I've never actually seen that before.


Click latency is perfect. In this picture, you see the latency as compared to the Zowie ZA11. As the winner, the Scream One's buttons were on average 7-8 ms faster to respond than those on the ZA11. This result means the latency is similar to current Logitech mice, which define the current gold standard.

Scroll Wheel

The wheel uses a mechanical encoder, which gives very nice feedback for scrolling, but the wheel's click felt unsatisfying to me. There were instances where I was given audible feedback of a click with the wheel without it actually clicking. This typically happened when I tried to press the wheel with my index finger coming from the left. The axle of the wheel makes a clacky sound before the switch actually actuates. Pressing straight down works quite well, but this behavior gives the wheel a cheap feel for its click.

Also, the transparent sides of the wheel are very smooth, which sometimes had me glide along the wheel instead of scrolling with it, especially with dry fingers. I believe that if you use a 1-3-1 grip with the middle finger always on the wheel, this wheel will be great for you, but if you are like me and scroll with your index finger, you'll probably have to get used to it.

Cable

The cable is braided and relatively stiff. I'd recommend getting a mouse bungee or using another cable-management solution because this cable by itself causes quite a bit of drag and resistance if it snatches onto something. In this regard, Zowie has the upper hand with their nice and flexible rubber cables.

Mouse Feet

The stock feet are evenly placed on the bottom of the mouse. They have rather straight edges instead of rounded ones, which sometimes increased the drag for me, especially when moving the mouse downward. Otherwise, the glide was quite nice.

Surface

The sides of the mouse remind me of the old WMO texture, which is quite nice to grip. The top coating seems like it consists of a soft-touch rubber, which feels very good with its only downside being that your skin oils will leave marks on the mouse.
