Lee equipment is built to meet a price point. Much of it is excellent, some is fair, and some isn't very good, IMO. I strongly dislike Lee's scales, for instance. Yet their rifle dies for military calibers and their carbide handguun dies are great values, even if they were priced higher. The Lee case triming system is the best case trimmer on the market, as far as i am concerned, and the least expensive.
Lee presses are not as durable as any others. They will wear faster, but the average handloader will not wear one out.
