I opted for ground shipping and my CatGenie arrived in three days! The directions were very clear, and it was so easy to set up, took maybe 10 minutes. My cats watched us set it up, and were transfixed when we ran the test cycle. My younger cat, who is so skittish he hides for hours after we vacuum, went right in and started using it! The older cat was the problem, but I called him in to see the younger cat using it and after that there were no problems. I am so very impressed by both the speed of the shipping and the quality of the product. If you have any qualms about dropping the cash to purchase the CatGenie- please rest assured that it is worth every. Single. Penny!
