Good: small, nice installation bracket, easy to set-up
Bad: Loose part inside, rattle when you shake it, make more noise than other lower prices unit, time based , so don’t expect precision, app doesn’t not allow a precise time feed, wich is required when you need to stop the skimmer during 1hre after feed. You can only spread the feed over 12/24 hres, day or night. If mfg listen, this need to be rectified
