After approximately three months of normal use, the left-click began to show extreme signs of being defective. Random double-clicks from only one click press, and failing to register holding the left-click down either.
Product has and is under warranty, however Logitech support has proven to be terrible with poor communication and task resolution. I contacted them and explained the situation, and instead of a solution to my issue, they gave me a gauntlet of tasks to put my defective mouse through to convey to them that it was indeed faulty, including making a video for them, which I refused citing that it was ridiculous.
Would not recommend this mouse, or any Logitech product. You will likely not receive proper help should you need assistance from the manufacturer. I still have not received a refund nor replacement.
