Bests & Worsts Reviews from Amazon

I've owned three of these mice of late, and both have run into similar problems. I will preface this review by stating that while they work, both mice functioned well. I like the size and shape, the extra buttons are useful for my editing work, and the mouse is precise and responsive. Most important to me, it's comfortable. But with both mice, they would stop registering input or create input of their own. My last one acted like it was haunted, but it was out of warranty and I figured it was easier to just replace it. This one is only a couple months old (a replacement through Amazon for another purchased one), and will no longer accept a left-click input (and will actually randomly toss in its own). It's not the receiver: right now, I am using the keyboard I picked up with the original mouse and an older mouse through the Logitech unifying receiver. That's right, I've got a four year old mouse that outlasted this model three times. Logitech makes great products, ordinarily, but I cannot recommend a model that has malfunctioned on me three times--especially since it's failed in roughly the same way all three times. I've contacted Logitech support, but I'm buying a different mouse in the meanwhile, because the loss of functionality is too much of an inconvenience to keep suffering. I don't give this product a bad review lightly. I wanted to like it so much I dealt with two bad versions.
