Lids don't fit canning jars well
These lids work really well once I managed to wrestle them onto the jars.  They're designed to fit wide-mouth canning jars, but the threads are poorly designed so they don't screw on.  You have to pop them on by pressing down pretty hard.  However, they do work really well.  I like them better than the all-plastic ones because water drains in and out of them easier.  With the all-plastic ones sometimes the surface tension makes it diffcult for water to pass through the tiny mesh holes and I have to unscrew the lid to rinse the seeds, which is difficult to do because the threads on those also aren't designed very well and I have a difficult time screwing and unscrewing them.  But both kinds do the job they were meant to do.
