Query: Worst wiper, just lasted for 2 weeks, flew off the vehicle in light rain

I will tell you, this is the worst wiper I have bought, it just flew off the vehicle when I was driving @40mph in light rain. The little plastic which holds the wiper was broken. You can imagine after the wiper flew off, I had to drive back in that rain by really struggling to see what is in front of me. Please don't buy this as it is a serious security issue when driving in rain. It just happened to me and I wanted to let everyone know this as I understood how difficult it is to drive if your wiper is broken, when you are 30miles away from your home and when the rain is never stopping.
