I have been using the Cat Super Feeder to feed my cat for about two months now and I want to say that it has functioned flawlessly. I find the feeder to be a well made and well designed product (and isn't it nice to find a quality product which is made in the USA ).I relied on the manufacturer's video during assembly because I tend to respond better to a visual guide. Assembly took some concentration, but everything came together fairly easily, and I was relieved to find that the final adjustments I had to make for my cat's particular brand of dry food were not difficult. ( I did fine tune my initial settings after about two weeks).I bought this particular model because of the many positive and helpful reviews which I found here on Amazon...they convinced me that spending a bit more than I had initially planned would get me a better product...and it did.
