I put this on my Gravel Bike (Sram Rival 1X drivetrain) to give me a little more gearing for steep gravel around here. Easy to install and didn't have change my chain either. Bike came with a 32 but the 36 just gives me a bit more help when I need it.
It's great to be consistent and use SRAM throughout the entire drivetrain. Thus, I purchased this cassette for my cyclocrossgravel grinder bike. No issues, everything works like a charm. I needed the extra gearing for Rasputitsa (ouch). All's well that ends well.
I live in WA and we do have some longer climbs so I wanted some extra gears as I do more fondo's. This gearing gives me more range to climb with less pressure on my knees than before. I ride sram 1x on the front and this gives me everything I need on the low and high end.
