Exactly what I needed. Product performed as expected.

I put these on an old chestnut stump that I'd previously tried to burn out. I had numerous 1 3/4" holes drilled in it about 4" deep, filled them with pellets and put warm water in the holes so they'd soak in. I covered it with plastic so rain wouldn't wash it away, but 10 months later I don't notice any difference. I still gave it 3 stars because on other wood it may work better. Other wise, for chestnut, I'd give it 1 star.

This is good stuff - for stump killer...and it makes a good smoke screen. By itself, it is not flammable when mixed with some sugar and it will burn very hot and make lots of smoke which helps keep the mosquitos away..
