Review: Love the temperature display - This heater works well for my small tank. I love being able to see what the temperature is for my fish.
Review: Great for the price. - I wish they had a separate probe for temperature, but I don't know that it makes any difference, I've just always used that style. I am using these in both 5 gallon buckets and 5.5 gallon glass aquariums, and they are really easy to set the temperature, have a bright and easily read display, good suction cups (surprised to see these small units come with 2 cups.) as a general rule I do not use glass heaters, but because these are temporary while I set up a sump, I didn't want to spend the money on titanium, and I don't even know if titanium heaters can be purchased at this low of a wattage. The glass seems plenty thick and the large rubber bumpers on the top and bottom stick out enough that they should be pretty durable. I think for the money these are great heaters, and even after I am done with them I'll be happy to have them around as backup. I've been running them for a few weeks so I can't speak to longevity, but they are doing their job, and as long as you do your part placing them properly in an area with good flow, they are very stable. Unlike another small cheap heater I have that came with a tank, these stay in place, so I feel safer about them not falling against some hardscape or getting buried in substrate.

## Features

- SUPER MINI SIZE – This aquarium heater is SUPER SHORT in length –It is only a bit more than HALF of the length comparing with the traditional fish heaters! The innovative super short length perfectly solves the headache of the fish keepers on the traditional aquarium heaters! Takes up less space, easy to hide, but in full power!
- INVERTER TECHNOLOGY – This aquarium heater uses the advanced inverter technology to heat water faster, while during operation it keeps water at a constant temperature in a more efficient way. Plus because of the inverter technology the fish heater has a longer life-span.
- MORE ACCURATE EXTERNAL THERMOSTAT – The in-built chips of this submersible heater keeps water at a constant temperature at an accuracy of 1F, much more accurate than the traditional knob-controlled heaters. The digital display of the external thermostat shows 2 readings – the current temperature and the set temperature – very easy to operate.
- HIGH STANDARD MATERIALS – Stable nickel-chromium heating wire, highly heat-conductive sand, housed by a shatter-proof quartz glass tube ensures excellent quality of this heater. Silicone protectors at both ends to avoid potential impacting with the fish tank glass.
- INTELLIGENT SENSORS FOR PROTECTIONS - With the multiple sensors this fish tank heater will stop working when the water level is lower than the minimum water level (DRY-RUN) or when the water temperature exceeds 97F(OVERHEAT). With the MEMORY FUNCTION, In case of a power cut, when the power recovers the heater will follow the last setting. You are free from “cooking fish”!
