not to start a razer vs logitech war but every single logitech ive ever bought suffered from doubleclick within 6 months of me getting it, and from what i understand their build quality has gone down recently. people always talk about how great logitech's customer service is, and yeah i mean they've sent me replacements before, but it seems like everyone also has to contact their customer support. by that i mean everyone's shit is always broken. if one of the major positives of buying a product is that the company talks to you WHEN your shit breaks, then maybe your product is just shitty.
razer doesnt have great customer service, but it's also not BAD. my current death adder is 3 years old now and not showing any sings of breaking, and that's with super nerdy super heavy dota2 and CS:GO use so take that as you may
