Mystery: Why Entry Door Handle / Deadbolt Sets Break on Rentals

[Jon S.]

Why do entry door handle sets break down on rentals? Its a mystery! The thumb latch seems to wear out and gets too loose on the sets I have been installing, and they are name brand sets. On my residence it never breaks! In the last year I've had to replace 25% of them. Any brand & style suggestions for a more durable set, which must incl deadbolt too? I mainly shop at Home Depot, but I could buy elsewhere if it will be better quality.
