The price was good. However after about 3 weeks I am not sure if the product is working or not. The light that tells me if the filter needs to be changed went out. Normally it stays a solid blue and goes to a solid red when it is time for replacement. I am giving it a chance to show something, so after about three months I will see what happens.
