So, I wanted for some time to try fancy ergonomic vertical mouse and randomly picked my favorite brand #Anker, because it was one of the cheapest mices but also I love Anker, I have couple power stations (with 5-6 USB slots) and this brand is not some flashy false advertisers "oh we are just the best of the brands", they just make very descent stuff

Mouse itself well built, just like I expected from Anker

First impression? I don't know. The feeling of awkwardness dissipated in like 30 minutes, after that I completely forgot that I use that mouse, it sits in hand like a glove, also noticed that now I left click with pointer, scroll wheel with middle finger and right click with ring finger. The only unusual behavior now is that I topple it sometimes because I try to reach something behind mouse (I keep water bottle on that side) because I'm still not used to height of this beauty

Conclusion? I'll keep it. It seems like my hand getting tired way less
