Query: Waste of money

Buying this product was a waste of money. If your travel is short it might make the cut as this product lasted for about three weeks but it has now stopped working. It gradually got worse and worse where I would have to spend a few minutes situating my plug just right so that the adapter would work. Now it does not work at all and I have had to buy a new adapter (that actually works).
