Is this any good?

I'm going to be picking up my G19 in about a week and I want to get some extras for it now. I want a super high capacity magazine for the range, but the one's made by Glock are over $50. I came across this one and am a little wary about the price:

Does anyone know if this brand is any good?

I handled one up the other day and the fit and finish seemed pretty good. I've read mixed reviews all around the internet about the Korean mags. Some people love and have had no problems and others have had problems with them. Some that said they didn't work would replace the springs and that seemed to help. I've decided to go back where I saw them and pick one up. For the price, I think it's worth it for a range mag.
