Lee has always been cheap stuff. I'd almost say carp.
But here and there their "stuff" has a purpose.
I mostly try to avoid them like the plague because I use what I buy quite a bit. Their stuff rarely holds up to quite a bit of use. But its so dang cheap its easy enough to replace when it wears or breaks.
Seems looking at the trimmer, had they only put a GOOD cutter on, instead of that cheap junky thing, it would work much better.
That said the way to trim is Giraud. IMHO. LOL
