Great overall device that can use some improvements. Amazing concept for post surgical relief. The ease of use is very dependent on mobility, type of surgery, age and if the “patient” has any sort of assistance. Perhaps raised or contrasting writing or physical indicators of HOW the lid fits, would be beneficial. A sticker warning to watch for water from either side of the hose would also serve to make it easier to be aware of how water drops or gushes may occur. The clips for connecting the hose don’t align easily and one must triple check to ensure it is snapped in completely.
