It is slow. I got by with it for years till I bought a large quantity of .223 cases. Then I needed something better. Here's what I did:

I bought the Lee universal 3 jaw chuck, and put it an electric drill with the spindle. Then I use the lee trimmer. I think it speeds up the process quite a bit, but best of all, I don't get blisters on my fingers. I can do a hundred cases a lot faster this way.

Be advised, that if you are going to do a lot of ammo, there are better options, check youtube. You're going to have a lot of money into it.

The other lee equipment works just fine, but it is slow. If you are going to do large batches of ammo, I recommend you at least get the three jaw chuck, because the lock stud requires enough torque to hold the case that you will get sore fingers.

For low volume loading, say 50 rounds at a time, the regular stuff works too.
