I have had a few rolls of bad monokote in the last few years. I can't remember the color, but it wouldn't go on for beans, wouldn't corner or anything. I ended up throwing all the rolls of it away. I was ticked at the time and we had a little frustration thread going, but since then, I haven't found any to be bad.

There are a lot that feel really strongly against it and some that feel really strongly for it. As stated by me and many others, use what you like and what works. When you come across a bad roll, you will know it. We all whine about the products we use at one point or another.
