Query: Flimsy piece of junk

I picked one of these up at Target for 14.99 and put it on my bike today and it is a piece of garbage. I'll be taking it right back.The mounting bracket is terrible and doesnt fit the lock well.The lock itself is covered with a plastic covering that moves around when inserting on the mounting bracket and covers the locks so you cant place the U portion on the locking mechanism.Once you finally finagle it the plastic cover around so you can secure it. The lock itself wobbles back and forth when you ride. It doesnt matter how tight you have it attached to the mounting bracket because it moves around inside the plastic covering.I don't think words can say how bad this lock is. I thought buying from Master Lock would be a good thing. I guess I was wrong.
