I really like the size and feel and small footprint of the container, itself. However, after receiving a replacement since the first one didn’t “click,” I found the replacement didn’t either. So I went on Amazon, where you can also buy this product and read a lot of the reviews. Apparently, many users have had this problem with the vacuum pump, and the company has sent out many replacements, which sometimes work and sometimes don’t. I like the container, whether the pump works or not, but I’m wondering if the ones that don’t function correctly outnumber the ones that do.
