Your mileage may vary with Razer products. I’m not sure how reliable they are now. But I have a Razer Naga Epic from over a decade ago and it’s still kicking and going strong. I am hoping it will still hang on for another ten years at least. It’s super nice.
Edit: I should also mention i probably got lucky? I’ve always heard iffy things about their products online. I’m not sure how mine hasn’t had any issues yet, but I try to keep it clean. The one thing I do need to do is eventually lube the scroll wheel a bit. It has a little squeak when I scroll.
