Threads don't work well.
I used it; it worked for my purpose.  However, I could not get it to screw<br />ON to a wide-mouth mason jar; finally found that plain brute force worked to<br />seat it securely on the wide-mouth.<br /><br />To remove it all I had to do was UN-screw it!  Go figure!<br />Disassembled easily for through washing & drying. Reassembled easily, as well.
