Although price can sometimes be an indicator of quality, it doesn't necessarily mean quality. I think this is especially true when the alternative higher priced product has a lot of "Brand Value" that can be attributed to the higher price.
They obviously put lots of thought into their adapters but everyone fails where the cable enters the charger - I'm about to buy my third in just over three years and the cable on my daughter's actually melted through where it shorted inside.
Why could they never be bothered to address this well know issue give them thought they put in?
