I would like to use this machine frequently.
This machine is difficult to operate.
I think it is a good way to save water.
In general, I would not actively use this device.
It can reduce plastic pollution.
I am not interested in getting a brand new bottle of water water so I would not use it.
It can help people develop good habits of protecting the environment.
Putting in a surplus bottle of water to get a new one is likely to increase water and plastic waste.
It is a very novel idea and many people will participate.
It costs more than it pays.
