To add to this topic...
At times I think that any manufactured product one buys has the potential of being a lemon no matter what company makes it or what their reputation for quality is. There have been instances where I've bought the same item from the same manufacturer and had them perform entirely differently. Quality control isn't perfect. Still, we expect a certain level of quality and are apt to get cheesed off when things don't perform as well as we expect. From there I guess it depends on what the manufacturer is willing to do to remedy the situation.
