Product review (3 stars): Good for an emergency.... Not a permanent fix...
If you buy one of these don't have the expectation for it to last a long time... I was in a pinch, short on cash and needed a quick fix. I was actually surprised by it, it lasted almost 10 months. If that's all you need then these are perfect.  If you want them to last years instead of months definitely go for the actual OEM part and make sure the Whirlpool/Kenmore name is printed on the box.  They usually run about $80 on here but every now and then they are 39.99 with free shipping.
