I went with the staples brand of these after using Avery just because it was a lot cheaper. They are just as strong and everything but are strangely harder to load with paper. For some reason it wants to stick going in rather than sliding smoothly. A small inconvenience for the price savings but there you go.
our pages are protected from spills and the sheets do allow easy reading with little to no glare. However the tops stick together making it a bit difficult to place pages inside the protectors if you have dexterity issues with fingers and/or thumbs. Overall a good solid product.
