Outstanding doser By Mike on 4/1/2020Mike would recommend this product to a friendI have the full GHL gear (Controller / KH Director and dosing). I am very happy with the doser in general. It is silent , reliable and can be controlled from the mobile app. It needs to be calibrated once(after the tunes are all in place). The only negative is the quality of the tube nozzles it comes with ( need to be cleaned of plastic bits before setting the doser up)
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?
