    Prompt delivery and correct item.

    Item is exactly what I ordered and came in a timely manner. Only confusion I had was brand. Original add said I believe Seedbarn brand but I recieved a Haifa brand. Again its exactly what I need so it doesnt matter.

    Works Great

    I bought 2 lbs of this for $5. This is the cheapest that I have ever found it. I just mixed it with some sugar and tested it. Works great!
