Bests & Worsts Reviews from Amazon

We bought this walker for my mother in law who is about to turn 80. She needs it to be able to get around her house and stay independent. After only 3 months one of the front wheels snapped off. This is the third walker we have gone through in the last two years. Does anyone have any suggestions of a quality product that might actually work? It needs to be foldable and light enough that she can put it in and out of the back of her Ford Escape.
