  • SO far so good except no green light
Keeps my water at 76-78 after a week of use and my only thing is there is no green light to say it is in idle mode as others have mentioned. Red light does come one when heating.

  • Great product, would recommend!
I love this heater for my bettas! I had bought a few about two years ago and one finally bit the dust. I just ordered a new one! I keep a thermometer in the tank so I can check the temp regularly and it stays between 76° to 78° for the fish!

  • There is no app
I got this product and it’s on and heating but the box says there is an app to use for temp checks etc. the app does not exist, so truthfully without a thermometer I have no idea what the temp is!!
