Razer sold me a mouse. It was defective with a well-documented manufacturing flaw. I returned it, on my dime, for a replacement. They sent me another mouse with the exact same issue. I returned it. They sent me a third mouse with a completely different known defect. I returned it. They accused me of being a scammer and a thief, and sent me a 'last' mouse, even though it was still under the warranty period of the first one.
The final mouse also had the same issue as the first one and started failing within a couple of months (the issue was a switch that was so weak that it was registering single clicks as double clicks, and wouldn't register a held down mouse button at all.)
Four defective product in a row and an accusation.
There is zero chance that I will ever buy any product from Razer again.
