This mouse (for left-handers) costs on average €30. Only in one store it costs €20 including shipping. For right-handers, it starts at €30. In my opinion, its quality is worth €70. I have 7 ergonomic mice and none of them compare to this one (I threw them away and saved my wrist). This particular one has very good reliability and movement. The others occasionally get stuck, but once a week they come unstuck in two seconds. Get it, it's a perfect choice! I'll come back. I have two of them and neither has fallen or been misused, but the wheel broke. I fixed it (don't do it if you don't have knowledge) and replaced it because I had a spare from another one. It's a very fake construction in an otherwise high-quality piece. I hope it was a material defect. I'll update if the other one breaks. I don't mind paying €20, but if I were right-handed, I would pay €30. I have mice that cost €15 and their wheel is perfect

I was looking for a second left-handed mouse and it's worth its price, a little small for my hand but very practical. You forget the pain in your wrist from using a mouse
