I have it and have mixed reviews.
First, it is noisy. But, my fish associate that noise with feeding time and swim up towards it.
Second, if you need more control, as others have mentioned, it is worth it.
Mine is set to turn off returns for 10 minutes and the skimmer for 20 minutes.
Third, as mentioned above, refilling can be a disaster. I disconnect it and do it over a plate, away from the tank. I’ve done it without pulling the whole feeder, and dumped half the contents in the tank. :(
Bottom line for me, the control with my Apex is worth it for me.
