سخان Superfish Preset Mini

The auto shut-off at 26°C is a lifesaver—I can leave it in my shrimp tank without stressing about overheating. It’s barely longer than my thumb, so it hides behind the plants, yet my water stays steady.

I’ve had this mini heater in my 5-gallon tank for a week and the automatic shut-off gives me real peace of mind since I sometimes forget to unplug things. Water temp stays exactly at 26°C, which my betta seems to love.

The 8cm length is perfect for my nano tank, and the fact that it runs on low voltage gives me peace of mind with curious shrimp around. Set it and forget it—woke up to a steady 26°C and the auto shut-off kicked in right on schedule.
