Wish other accessories features this safety knob design, it's very convenient.

Found myself racking the bar uneven and it being a pain to centre again when it's loaded, this is a pretty good fix for it and it's a good price too :)

Bought these on a whim rather than the sandwich cups, and the only thing I regret is that the M3 doesn't come with these in the first place! Superb idea - I'll be getting another set.
Dunno about longevity but it terms of practicality/usage (i.e. why you buy them), they are great.

These are perfect for shuffling the bar so it's centered properly before a lift. I don't use the safety knobs as they're a pain to add and remove and to be fair they don't sway that much if at all without them. Again really high quality from Mirafit and very happy with these.
