Getting the casette toilet in and out of the container can be very difficult, especially when it is full and heavy. Bear in mind, that when it is in, it has to line up precisely with the hole in the toilet and the lever that opens and shuts the gate. It could be designed a little better as most of the problems are caused by the bottom latch of the door, but once you know how to overcome that, it is fairly easy to get it in and out.
