Valid points, but doesn't matter if the sleeve doesn't perform its main objective at all.
Furthermore, it shouldn't be forgotten that sleeves are wear parts and you'll have to replace them in the not so distant future, but I knew what I signed up for regarding extra-sleeves and GW.

There might be a chance that I've just had bad luck and I've got two bad packs, not a rare occurrence with some manufacturers.
Either way, I'll not buy them again. (Shuffling is smooth tho).
