The plastic has proven to be scratch free over time, I really like that. The lids have amazing fit and keeps even liquids leak free.  I haven't had any issues with cracks occurring when the containers have fallen so far. 
The transparent look is simply brilliant, the ability to view the contents even from the thorough the lid is a feature that will always make me choose these containers. 
I intend to use these containers for storage throughout the house as well especially for organizing kids supplies- crayons,  stickers , small craft items. 
Perhaps even for my makeup essentials- cotton balls. small brushes,  eyeliners etc.
