( 2012.02.11 08:02 ) : This feeder works great as long as you fololw the directions and complete ALL the steps for setting it up. After programming the current time, you set the times you want them to eat, THEN go back to those times and select 1 rotation or 2, depending on how much you want them to have. The default is 0, so that's why it didn't work for me at first. Now that I have it programmed correctly it works great, right on schedule. The mounting bracket did not fit on the edge of my tank and it comes with double sided tape just in case that happens. But, I wanted to be able to easily take it down to refill/reprogram/change the batteries, so I used Velcro instead of the tape. The Velcro works great but the unit does lean a little to the side. I put a quarter under that side and it's level again. Be sure to save the directions for when you want to reprogram, because it can be a little confusing without them.
