They're very expensive for what they are....

A few months ago I downloadad the Tri-X and Kodak Gold VSCO filters for free (a special offer).
I'm about to uninstall them since I never used them.
One thing to bear in mind is that they add presets in several LR panels, namely: presets (16 presets each filter), curves (16 curves each) and Camera Calibration (2 & 1).
Personally, I don't like all that clutter.
