I honestly don't understand why manufacturers attempt to do this.
It's because the great unwashed has yet to realize "NEW & IMPROVED" translates to "Not yet proven to be defective.". Not only have they yet to realize this perennial truth, they never will-----thereby assuring the earth will keep on spinning----around and around and around-----thereby making work for street cleaners and those who feed upon them.
Sad but true------------
