While Lee doesnt make the best out there, they are the "economy" version for the reloader on a tight budget.
I have a Lee Auto Prime, I have used it for years with little to no trouble.
I also found that I had to "debur" it and lube it to make it work well.
Other than that, I have no complaints with it. I mean, what should I expect for 10 bucks?
Lee dies are a different story, I really don't care for the locking rings, and thier "precision" leaves a lot to be desired.
They are great dies to buy for a caliber that you don't load as much for.
I much prefer RCBS dies myself, they make the tiny adjustments a lot easier.
