I have used this container and loves it.  I like the fact that I can clearly see my food and its very easy to open with its easy to grip push button.  Its idea for anyone that has a hard time opening container.  Its dishwasher safe and helps keep my food from becoming stale.  It keeps my brown sugar from clumping which is very impressive to me.  I also love that it doesn't take up alot of space, its has an ideal size  for a 1lb of brown or confectioner sugar.  I recommend this product.
