This tube dispenser sounds like a great idea until you read the packaging and unpacking instructions on the Milky Spore box. As you will find, it is near impossible to avoid the dust related to the Milky Spore product as you are filling this tube. Second, the tube does not work that great even after I reviewed the You Tube video demo. in the end the tube does not hold up to the banging on the ground to get the spore onto the grass. The adjustable opening does not stay in the selected output setting and dirt get into the wholes where the spores come out. Stay away.
