I'm starting to look around for a new mouse for my computer, mainly because my current mouse has a slight flaw that I've fixed for the second time, but don't want to go about fixing it a third time again. This is the mouse I currently use, the Logitech Performance Mouse MX: I love the mouse, it fits well in my hand, it can use virtually any surface to track the cursor with, it's rechargeable with a mini USB wire attached to it.....BUT....after heavy use, it suffers from a double-click problem with the left button. So each time I want to click and drag a file from one folder to another, it sometimes double-clicks the to open up, or clicks something else and opens that file, etc. Basically, it's becoming less reliable to click and drag something. The issue is from a copper spring that's embedded in a small black box under the left click button. The copper spring flattens after some time of clicking the left button and holding the left button to drag files. Fortunately, I was able to fix the spring on the two occasions where I had to open up the mouse, but it was a pain trying to use tweezers and steady hands to get the spring in place after it was taken out (quite a few times having the spring jump and land on the floor). So....I'd like to know if anyone can recommend a mouse that doesn't suffer from the copper spring problem. My understanding is that Logitech has that same mechanism under many if not all of their mice products. I'd like to have a mouse that's about that size that can use any surface to track the cursor with, and hopefully not Logitech so I can avoid that issue again. That's unless such an issue will occur in the future again regardless of the mouse I purchase.
