The set up is simple. Fold up the 3 legs insert the collection bag (are not included) and do your thing.
Many camp places, bush camps, are now stipulating that you must bring a portable toilet to be able to camp. Whether you use it or not is up to you, depending on where you are, but without one you just are not allowed to camp.. if you take a portable toilet, these are large and bulky, and not easy to bring with you in many cases. The advantage of this toilet, is that it folds small, is very hygenic (no digging holes etc).
