As part of the OXO testing group I’ve been using these little containers for a few weeks. They are great!  The size is a little big for me to keep spices in but I use them for everything else. As I’m a widow and live alone these are perfect for smaller amounts of leftovers, making pudding and portioning out, homemade salad dressing storage-the list goes on.  
As a rheumatoid arthritis sufferer I appreciate the oh so easy pop up closer. No more struggling with lids that are hard to snap on or off. 
And cleaning is a breeze. Everything comes apart-especially the lids and is easy to wash and put back together. 

Definitely thumbs up!  Another great OXO design.
