Honestly? Many people hate it solely because its made by Lee. There are a few members here that will openly bash anything that isnt blue. Others will just hate on Lee. The fact is if it werent for Lee there are many that would never be able to get into reloading, or take it as far as they have.
I know, I may sound biased, and I will openly admit that. I have two lee presses, a lee scale, several sets of Lee dies, lee hand autoprime, lee autoprime for on press priming, etc. I have never had any issues with my Lee equipment, and will continue to buy it.
