I have had one similar to this one before. They work very well. Only took about 10 minutes to put together. What is time consuming is digging the deep hole that is needed. Just make sure that the soul is already moist. This makes digging easier. Use a square nose shovel for the top part (do this part first) to fit it into place and a post hole digger for the hole in the ground. Add one tablet weekly with one gallon of water. Make sure that there is always a little water in it. It makes the digestion work better.
better than bringing it into the house to flush down the toilet. just dump it down the hole and add water and the enzyme tabs every few weeks. hardest part was diggin' the darn hole! the bigger (& deeper), the better.
