Review on 🐠 Jebao Doser 3.4 WiFi 4-Channel Auto Dosing Pump for Saltwater Reef Aquarium in White (Doser3.4) by Holly Smith

2 out of 3 channels not working after 3 months - should be dosing 45ml/day, they are dosing 3ml/day. The pump is calibrated. Manual dosing works on all channels, manual dosing from the application works, scheduled dosing doesn't work. The app, which I would rate 2 out of 5, is not very intuitive. I tried to contact customer service, ended up on a website that only sells jebao ponds. Pumps; Jebao China website does not display email.
