I have used Snapware plastic containers for a couple of years. Except for just a couple of pieces I have been very happy. I even ordered additional pieces. Recently my wife bought some more at Lowes or Home Depot. They are terrible. They are not the same sizes as original so won't interchange with originals. The lids are terrible. The seal keeps falling out and they won't even stack well on themselves. I noticed the new ones do not have the original copywrite logo. Could they be phoney?
