Input:
Performs OK optically, but very difficult to get off once screwed into my UV filter.  It tends to take off the UV filter with it when I try to remove it, so I put it on  looser, but then while I was adjusting the polarization direction while overlooking a bridge it came off & fell 20ft to its death.  (Well technically I don't know whether its dead, since I couldn't find it).  The knurled part needs to stick out a little further to allow a grip on it.  There needs to be a way to secure it while making it easier to remove when done using it.  Oh well, now I have an excuse to buy a new & different one hopefully without that problem.
