Tested my filters by following the method outlined in

I have four filters: 1 Kenko Pro1D, 2 Vitacon, 1 Non-branded, which came as a free gift when I bought my Tamron 17-50 online. Only the Kenko filter passed the test (i.e. had minimal effect on the flare). All the other three turned to be junk, which, btw, means that they resulted in crazy flares as compared to when the filters were off.
Posting this here just in case some CSers had the same doubts as I did. Cheap filters basically ruin your money spent on expensive lenses... Or is that an exaggeration? Please enlighten me in case I am wrong.
