I've done upwards of 2500 dives in mine
The fins themselves are virtually indestructible.
I strongly recommend getting the bungee style foot straps. They are very comfortable, instantly on or off...and nothing to go wrong with them. The straps have lasted perfectly on mine so far (and that's a lot of time in the water). but if the elastic did perish, then it quick and cheap to swap in some new elastic.
I'll also vote for Force Fins and recommend the bungee strap. Don/doff is laughably easy. Good power and control underwater, high-vis options, and comfortable.
I do get cramps with them, but only after ~1 hour in the water -- it's cold here.
