Just got my Kana v2 White from takasta, shipping was extremely fast. Only took like 4 days from HK to Europe, and there was no customs fee because he declared it at 25$
This is my new favorite mouse without a doubt. Having used the Deathadder BE I was used to having a crappy scroll wheel that would skip a lot, the mouse feet are too small imo and the glide isn't really that good, even with new feet stacked on top of the default ones. The sensor was as you already know great, but it had some weird skipping on some surfaces, I'm pretty sure all of the DA's have that but it's a small pool of surfaces that it skips on in a weird way. For example if I lift it up like 0.5-0.7mm from the pad it starts jittering on Tt eSports Ladon mouse pad. It also had some weird tracking issue where if the pad wasn't rotated 90 degrees it would skip on occasion and go downwards instead of going straight. No problem with the Kana v2 there, the tracking is excellent and the lod is a bit higher than the DA. Now the most important part for me is the grip and the build quality. Kana v2 is imo a lot better in both of those areas, especially the build quality. It's really solid, both mouse clicks are the same (DA had uneven clicks), side buttons and scroll wheel are also good and overall the build quality is excellent. The only thing that's iffy is the default teflon pads, I'm pretty sure it's not pure teflon but some sort of a mix between plastic and teflon. As soon as I added the Tiger gaming feet on top of them everything was much better. I'm not sure why people think that the glossy version has a weaker grip, because this thing is extremely grippy in my hands, whether they're mildly sweaty or not. It's much better than the coating on DA BE.
In conclusion, this mouse to me feels extremely good, probably the best one you can get right now if you like it's shape.
