We will start at the top! I debated on buying this for almost 2 years. I finally purchased mine Cyber Monday. I did my research and here is what I found. First I called customer service to get some info. They were polite but not very helpful, and I had to leave a message and wait for them to call me. Online I loved everything. ordering was very easy, and I got mine at a discount since I signed up for e-mail. Delivery took 5 days, not bad in my opinion. Set-up was easy, I had pre measured where my little box was currently at (between washer and wall) so i was ready to go.only problem during set-up was trying to store the extra discharge hose under the unit. Testing the unit was easy and watching it do its thing became a family event. Setting the units wash cycle was a little difficult, but once you give it some time you can figure it out,. All in all so far I am loving mine. My cats began using it right away. I do like how they include tips on how to transition your cat into using the Catgenie. All in all the unit is very high quality and I think it will be a valuable addition to my home.
