I got the 8.5x11 20lb Copy paper in the 8-ream box, and it met my expectations for simply being standard printer paper like you'd expect and have had ZERO problems with them feeding or printing from my printers, single or double-sided. The paper is just regular light paper, doesn't seem too thin or cheap. Its as pliable as wrapping paper, and not a thick card stock. I filled my tray in my HP LaserJet Pro MFP M477fdw to the brim, and have been printing for standard home office use, usually double-sided, and never having a problem or second thought about the paper quality. I don't get any unreasonable bleed through other than what you would expect to faintly notice on two sided printing if there is light beneath the paper.After looking through a lot of choices online, and reading reviews of every brand and variant, all of which with some scary reviews out there, I gave this a try, hoping for just decent standard printer paper that works. None of the fearful review claims came true for me. Not unexpectedly thin. Zero jamming for me. I like that it comes in a convenient box for easy ream storage, shipped to your front door, and a pretty decent value. If I had one complaint, is that the paper wrapping on the reams themselves is thin and tears easily on the sides when the ream flexes as you pick them up. It doesn't really matter as the box itself is protective. But a thicker ream wrapping paper would feel more sturdy and protective. But I do like the paper sleeves as they are easier to use a partial ream than the store-bought clear plastic sleeves that shred to pieces when opened.Personally, I've had some thicker paper before that feels more sturdy and rigid than this. I've had GP paper that I just loved because it felt so sturdy and worked as well, and I've had some HP paper from a local store that felt like stronger card stock. I thought I had 20lb paper before, but maybe it was heavier stock. I wouldn't say this feels "premium" in nature. But as 20lb copy paper, I don't think I can expect more than being what it stated, arriving in good condition, and just working. Although it is hard to say I "love" this paper, there are no flaws to knock off a star in my book. If you really want a paper to feel more rigid than regular paper, I think you simply have to go >20lbs card stock.
