My 2 cents/review as a dad who games with his kids, an esports coach for four teams for six years, a computer science teacher, and a PC scratchbuilder/overclocker/hardware enthusiast:
Razer Huntsman TKL w/ optical switches is the best keyboard I've ever owned, hands down. If you haven't tried an optical switch keyboard you should! But is so sensitive it takes some getting used to. Durability and cleaning have not been an issue even around younger kids who snack while using it despite being told not to. Comparisons to HyperX Alloy Origins and Corsair and Razer's older keyboards with normal mechanical switches, which were all fine but not the feeling that an optical switch provides.
Most of the Deathadders I've owned have similarly been great, although on a recent one V2 has the grippy rubber sidesections delaminating after fairly little use. I wish it were a bit lighter, but that's not enough to make me change to another mouse. The original one from 2011 or so finally bit the dust in 2022 after hard continuous use, so I'd anecdotally say durability is good.
Razer headsets sound pretty meh, the Dolby plug-in is truly terrible, and my kids have broken two. Sennheiser or Beyerdynamics are much better.
Razer Kiyo Pro Ultra webcam is a noticeable step up in picture quality from a Logitech Brio, Logitech 922, or generic Chinese brand 4k webcam, especially in less-than-ideal lighting conditions, but it is also extremely expensive, so niche product.
The old Razer Turret was super expensive, had trouble with the shorter than expected range of its wireless and Bluetooth connections, but held a charge and was a great wireless lapboard/mouse combo. The new wireless ones have amazing polling rates but shorter battery life and are less convenient as a portable platform, but the connection range seems to be fixed.
Prices are competitive if you wait for the occasional sale through their Amazon store. And it would be cool if their software required less frequent updates and had broader RGB setting compatibility, which I think is really the main point of running it in the first place.
