Thata my fear with the jebao. I'm gunna see what my buddy has for a price on the bubble Magnus first.I’ve had the Jebao for little over a year, do a random test from time to time to make sure my pump is dosing accurately and to this day hasn’t had any issues, and is still dosing accurately, it also has a internal battery Incase power outage, what does kinda scare me is if the pump were to get stuck on it will dose for 30mins before turning off. I’m personally thinking getting a WiFi pump to monitor dosing to make sure this doesn’t happen. Since 30 minutes on would be a nightmare with ati being concentrate
