Keyboards, headphones, laptops, a handheld Steam Deck imitator, and various other RGB gamer shit. All of it is trash. Their business model nowadays seems to revolve entirely around upselling Aliexpress quality Chinese garbage at premium prices and then methodically denying every single warranty claim for defective and DOA product using spurious excuses. Oh, and their driver software is crap. And their products are consistently behind even Logitech on the features you get for the price.
Through no particular intentional means, I am now a Logitech convert. For mice and keyboards, their stuff has always been consistently reliable for me, their "G" series driver software is significantly less irritating than Razer Synapse, and most of their stuff is cheaper as well.
I think in my lifetime I've trashed four Razer keyboards, at least as many mice, and two pairs of headphones. All of these died early deaths -- within weeks, sometimes a couple of months at the outside. Every time I tell myself this time will be different. It never is. I don't buy their shit anymore, and I don't recommend anyone else do, either.
