Query: Poor build quality

I purchased and installed three of these for my touring bike. The cage that I most frequently pull my water bottle from broke at the weld after about 3000 miles on my bike. Not bad? We have four "plain Jane" no-name cages on our tandem with 13K miles that are all still going strong. I emailed pictures to Planet Bike about the broken weld and they sent me a replacement, no questions asked (NICE customer service!).HOWEVER, the replacement cage only lasted 3 months before the weld on that broke at the same spot as the first.The Planet Bike SuperFlash is an incredibly bright taillight (drivers have said it looks like an emergency vehicle light); the Planet Bike fenders are perfect on our tandem; their customer service is painless, but in my experience, this cage doesn't have the metal - where it needs to be.
