I don't mind as long as it doesn't take me out of the story. It probably helps that I don't recognize most products being placed, as I do not know ads.
Thinking about it... product placements do introduce an interesting dynamic.
TV shows I watched in the past often went out of their way to change brand names, for example Somy instead of Sony, WacDonalds instead of MacDonalds etc.
This is done to avoid copyright infringement, I think.
