Summary: Didn't need these mice in a hurry, so a took a chance. Nearly a month later they arrive smashed and not typical quality.
Pros: Great Price, shipping was free.
Cons: Item took 25 days to arrive. was shipped in a bag instead of a box so the packaging was ruined. the poor printing on the box and lack of sealing makes me suspect that items may be counterfeit. The mouse feels cheaper and lighter than the U.S. counterpart. Not typical Logitech quality.
Pros: Decent mouse, cheap to replace b/c it's on sale often
Cons: You have to replace it often...it's not durable in any way, shape, or form. The copper bit in the mouse button, (the thing that makes it click) is very cheap. I've worn through two of these mouses in too short a time. I won't be buying this one again.
Cons: I bought this because my last mouse started double and tripple clicking, and I thought Logitech made quality products. This mouse started with the same problem after 6 months. Do yourself a favor and buy a mouse with good warranty.
Summary: Its just 3 days and the mouse starts showing signs of trouble. Click and drag on a PDF and Google maps (or wikimapia) sticks the mouse pointer on the same spot on screen even after you have released the left-click button. This happens intermittently.
