depends on where you shoot, and how clean you keep things. mine is about 3 years old, and the housing is wearing pretty bad. the ram is getting sloppy. granted, where i shoot, is ALL sand, and occasionally, i deprime a case that has sand in it. when this happens, the sand goes down the primer hole, and right between the ram and the housing, which, of course, gouges the nice soft aluminum housing, and causes wear. but, in al honesty, no matter what, any dirt or debris (even just the spent powder and primer junk) will end up in the bearing surfaces and cause wear. personally, i would look for something that does not dump the dirt onto the bearing surfaces. the lee classic cast iron press would be much better. when i bought mine, i did not realize how much i was going to use it. my press probably has somewhere in the neighborhood of 30,000 rounds through it. when i replace it (soon) i will probably look into something other than a single stage press. i will then use this press strictly for depriming.
