CORSAIR HARPOON- RGB Gaming Mouse

Where to begin? Out of the box it was a nice mouse and I was initially pleased. However, it quickly became apparent that the iCUE software was utter garbage. Across multiple PCs, the software would fail to load, or load then fail inexplicably. When iCUE would work, it wasn't always applying my defined RGB profile, or would for awhile, then suddenly change LED and sensitivity settings for no reason, then later revert. Eventually I became fed up enough to disable the iCUE software, which one might think would result in a mouse with no lit LEDs. However, the default appears to be a glaringly harsh, white-green light which caused me to cover the mouse with something when I would go to bed or else it would illuminate my entire bedroom. Terrible design decision there, Corsair. The default state should be no LEDs illuminated. After about a year of use, the left mouse button switch began to exhibit problems with not always registering clicks. This eventually worsened to the point where I tossed the mouse and resolved to never buy another Corsair product, which is a shame since I've been a Corsair fan for many years now. Shame to see a company fall so far when they were once synonymous with quality.
