I have had a variety of issues with mine. All but one dog related.
It's been piddled and chewed on by puppies. Still works after 3+ years.

A year and a half ago I left my computer in a crowded room plugged into the wall and when I unplugged it the prongs seemed to be loose. Not sure what happened in my absence. Well, they got wobblier over time and then independent of each other and I had to support the prongs each time I plugged in. I was afraid I was going to electrocute myself! Then I remembered my DH had two cord for his and only used one of his short prongs. He gave it to me. I feel safer now but this weekend my adult male dog knocked it out of the outlet and bent one of the prongs. I am afraid it is all starting over.

Hope you get a cheap solution.
