Buttons, Scroll Wheel

I didn't have high expectations for the main buttons, but they turned out to be a pleasant surprise for sure. Their pre travel and post travel are negligible, and the actuation feels quite nice. Huano switches tend to be a bit stiffer and less tactile than Omrons, and this can be felt if you're very much used to the latter, but overall, they're still great. The main switches are rated for 20 million clicks.


The scrolling has a medium resistance and is quite tactile; the notches are well separated, but it's still relatively easy to scroll through the steps. I've mentioned some stem misalignment under the build quality section, which makes some of the steps a bit harder to scroll through than others, and this cyclically repeats, of course. Though noticeable, it isn't distinct enough to bother me. The encoder is made by F-Switch and is 13 mm high.


The button beneath the scroll wheel is a tad harder to actuate than average, and again, with the scroll wheel in certain notches, it's lighter than in others; I'm sure not all copies suffer from this issue, though. The switch used here is a standard 3-leg one with a "W" branding I don't recognize.


Both side buttons use standard black shell-white plunger Huano switches, and as far as I know, these have a nominal lifespan of 10 million clicks. These buttons actually feel great; their actuation is nice and tactile and devoid of a lot of pre travel, which is often a common problem with side buttons.


Moving on to the CPI buttons, these have the same Huano switches as those beneath the side buttons. They stick out just enough from the shell for their actuation to be comfortable, but are not in the way, so no accidental clicks should occur. They feel just about the same as the side buttons, too.

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

Mouse Feet

The mouse feet pretty much feature the same design as on the Zowie EC models, but I am pretty sure their feet aren't interchangeable. These stock skates are pretty good; their glide is smooth and even, but I don't reckon they would last as long as pure PTFE aftermarket feet. As can be seen in the pictures, they are just inside the feet slots; the applying accuracy could be improved a bit. Not a problem, of course, it would still be a nice touch.

Cable

I've only seen a few worse cables in my life. The one on the Dark Project mice is pretty awful. It is not very thick, but braided and lacks flexibility. I'd definitely suggest using a bungee, or affixing it somehow so it doesn't touch the mouse pad as it generates a lot of drag otherwise. It is 1.8 meters long, and the USB connector is gold-plated.

Disassembling

Disassembling the ME3 is easy, but you should be careful because two ribbon cables hold together the top and bottom parts. The three screws are beneath the mouse feet, and the glue residue is unfortunately extremely hard to scrape off on this mouse.
