Bought a 'universal' glass suction cup lifter online for $85... it held for about 3 seconds before dropping a patio door panel onto my sawhorses.

Right, "universal" is just marketing speak for "we didn't want to make different sizes." The real problem is those cheap lifters don't have a good vacuum seal on textured glass or anything with a slight curve. They work fine on a perfectly smooth tile in a showroom, but on a real patio door with a few years of grit and grime, the rubber just can't grip. I've seen guys try to use them on tempered glass tables and the pad loses suction as soon as you lift from one corner. It's almost always the small 4-inch cups that fail first because they don't have enough surface area to hold the weight. Basically, if it's not a name brand with a manual pump and a gauge, you're just betting eighty-five bucks on a clock ticking.

Yeah, "universal" is just code for "doesn't work right on anything." I saw a whole thread about those cheap lifters failing.
