I've had the same clam for years now (like 5 or 6 anyways). No issues that I didn't cause from my own stupidity, but it still works mint.
I also have a cheapy pop up I got from costco last year that has been great so far. Only one season on it, but I have no complaints except that its orange.....works good, easy set up, and has held up to some serious winds and cold weather.
