Query: Nelson 5210 timer mate watering switch

I've searched everywhere for this product (locally and on line)and can't find it...The manufacturer stopped making them, so ordering them through Amazon has cost me a lot of time and frustration with nothing to show for it. This product would be great, but since you can't find them, all the glowing reviews in the world won't do you any good. I give it 1 star due to unavailability.
