We have used one for 20 years and LOVE IT! We also read about the soil type, and in Alabama were we had it, it was HEAVY CLAY, and it worked just fine. As others have said the only thing is you must follow the directions of add a quart of water dailey and enzyme weekly. We found I tub of the enzyme lasts a year! It also ogt pretty routine that when I would bring his food out, we had an old milk jug that was marked at a quart and would just feel the dooly up then. Never had a problem. Probably the only problem with sandy soil would be digging the initial hole cause you have to use a post hole digger and go down almost 4 feet.
When we move to TV fulltime instead of weekends we will definitely be putting another one in. As I said me and the wife love them.
