I just got some really shitty ones from China for like a dollar, and even though they're only 40A hardness (very soft and squishy) I feel like, as someone who mashes the keys pretty hard and always bottoms out, that they're helpful in conserving energy and correlating the bottom out of the key with the actuation point. It feels better to double tap with the o-rings than without. It's not a groundbreaking difference but the improvement is immediately noticeable.
O-rings are kind of a rarely visited topic around here so I felt like putting that out there. If you double tap, using o-rings will probably improve your stamina and your accuracy by a small degree. They cost basically nothing so you don't have much to lose by giving them a shot.
