Perfect for detecting animal urine spots
This worked surprisingly well.  I foster cats for a local animal shelter and when they have accidents I am motivated to find the areas quickly.  I was just using a UV light, which found them, but once I put these on, the spots popped with really sharp lines.  It was just like you'd see on CSI.  The contrast was terrific.  I am very happy with this purchase and recommend it for that purpose at least (identifying animal urine stains).
