I like that site for comparing products. I even left a review on the Primo Lump back in May. I've been using it since I got my Primo XL. It's a bit pricier than some of the others but it's a 20 lb. bag and I have weighed a couple since reading what the website had to say about it and it is consistently 2-4 lbs. over so if I get an odd piece here and there I'm not complaining. I've been through about 20 bags and I think it's the best I've tried yet.
