I have bags for 2 subs, 2 mains and 4 monitors. As much as I loved them when they were new, after 2 1/2 years they are quickly becoming unusable. Broken wheels, broken zippers, extendable handles that are frozen. One bag has a seam that came undone so when you zip it, it still flops open.
Maybe that is the expected life span of these things, but at over $1000 to replace them it's kind of hard to swallow.
