Purchased my first ones on sale to see if it would work in our house hold.  I babysit a very independent toddler who  insist on serving himself  getting his cereal prior getting the dispensers I had a mess to clean plus avoiding breakage.  Now the they sit on my counter top ready to go.  I only had to show once how to remove the cap and put the bowl under the hole, turn knob the cereal releases in the bowl.  I have to replace the cap because you have to hold the top to close that is why only three stars.
