Product review (1 stars): Lasted 2 Days!
Unfortunately, I had the same problem as others that posted previously!  I tend to use my own judgment and expect the best from a product, but in this instance, I was wrong.  the Cut Out Fuse was installed on a Saturday, by Monday it was no longer working.  I'm very disappointed!  However, I will be returning for a refund.  Now, I'll need to locate the fuse at a reputable home improvement location.
