Until now, I had been using a water purifier from a different manufacturer. It was good, but I thought I'd give this one a try if I could buy it at Nitori, so I bought it. The instructions for use are easy to understand, with pictures, but I thought it would be better if the instructions for removing the lid were written at the beginning. The one I was using before was the type that opens from the top, so I thought this product would be the same type, but it seems to be a sliding type, so I was like “Eeee! I was like, “Is that how you open it?!” The instructions say to prepare the main unit set at the beginning, but the lid is already open at that point, so I would like the instructions to also include how to open the lid.
