So far I have broken every piece of Ronstan kit I've owned (mainly downhaul and spi halyard stuff).
Have also broken some small Harken blocks but this was more due to wear and tear.

I saw this product in a surfshop yesterday and thought that would be great to fit as an alternative to footstraps.
It would be much safer since your feet are not stuck like in footstraps, what do you guys think?
