Operation has been confirmed. As shown in the last three images, the lid doesn't close tightly and is slightly raised. Pressing down firmly on it for a few seconds after closing it reduces the lift, but it shouldn't significantly affect use even if it's raised. There is no box or instruction manual, so please download them from the internet. It has a safety feature that stops operation if it falls over. Removing the water tank requires a little technique. Insert your finger in a sliding motion towards the back and then push down while pulling towards you to remove it. Everything in the images is included. This is a used item. Please refrain from purchasing if you are sensitive to imperfections. Thank you.
