I really like these polarizing filters, but I have a couple gripes and maybe it could be my fault.
a) the filters don't seem to have adhesive, although they do have some kind of layer or maybe the surface is just similar to cling wrap in that it seemingly magically adheres itself to the screen's surface, but I sometimes find that it doesn't stick well enough to the screen causing it to come off the screen if ever I remove it.
b) they give a greenish tinge to my GBPs. I thought these linear filters were what I was supposed to be using for a GBP, but maybe they're supposed to be greenish.
Regardless, I think these filters are definitely worth the value and particularly, since they're from HHL I can't help but come back for more due to their quality and great shipping services.
