It has worked great for me. A bottle will last a couple of years. The secret is to not cure an entire can of corn at one time but what you will use in the next two days.
Which btw, I make fresh corn for each day. I have data to prove it makes a significant different.
My pro-cure order should be on the porch when I get home, ordered the regular cure and also the pink cure, some orange dye and a couple of defferent scents. I'm excited to see how they work! Of course the meal worms will be on a hot standby .
