I’ve only taken advantage of this once. When I had VR, I got some utility program because it advertised being able to do something I was trying to do (I don’t remember what exactly), but it didn’t actually do that thing. I requested a refund after like 20 minutes of using it and it was pretty much instantly refunded.
Damn good policy, as long as you check out what you buy pretty quick to make sure it’s what you want, IMO.
