Product review (5 stars): Don't Think Just Buy it for your families sake!
It's inexpensive, it's easy, it works fantastic, it could save your life by removing a fire hazard.  Unless you are a complete klutz or do not own a drill you can do this and not only save a bundle over paying someone else to do it, but save your life.  Do you know of any other product that can make that claim?  And no I don't own stock or anything of the sort, indeed I was dubious that being so cheap it would work.  But it does work, besides even if you don't believe me what's a few bucks to try and find out if it works.
