Precise and Quiet. Very reliable. By d on 10/14/2019d would recommend this product to a friendGreat build quality (as you'd expect from GHL) Set and Forget dosing pump! I own 3 slave dosers and 1 Stand Alone and they work flawlessly.
Others have mentioned the app and the mobile/web app has had plenty of updates. No need to worry there. Its very easy to use and setting up a dosing schedule and ATO/water change functions are also easy-peasy at this point.
One thing to bare in mind: If you don't own a controller the Doser 2.1 SA (stand alone) is what you're looking for. It doesn't require a controller where these Slave Dosers require either 1) an SA doser or 2) a Profilux controller brain
Good doser but horrible software/app. By Philip on 7/25/2018Philip wouldn't recommend this product to a friendOwned v2 of the doser for almost 2 years. It works great for the most part but the software and app are a pain to use. The App especially really need an update!! Seriously, how do you sell a $400 doser with such crappy app that hasn't been updated for years?
