Do the glass beads leak out over time?

It's the most common durability complaint across r/WeightedBlankets, where users note that many Amazon blankets eventually leak beads 'so you wake up in a pile of sand.' One ZonLi owner reported bead leakage after about two years. Tighter-weave, smaller-pocket construction (YnM advertises 2x2-inch pockets) is what communities point to as more leak-resistant, though it isn't foolproof.
