GuanoBoost Spreader

This works very well. It has four positions which include three different size holes and a close position so that extra fertiliser/seeds can be stored. As you shake the container, contents come out onto the shelf that has ridges on it which evenly distribute it. It made applying fertiliser to my lawn very fast and easy. Due to its 2.5L size you will need to refill it a few times but if was any bigger it would make it too heavy when full.
