6 weeks after my last review it seems as though the 78 degree green LED is now burnt out so it basically becomes a normal heater until the temp is too low or high when additional leds will flash. The other issue with this is if you ever have to set it as you'll have to guess where the light is supposed to be flashing.
Just for clarity, the green light normally stays on that matches the set point while it's plugged in. Lights will flash at the current temp when the unit is actually heating.
-2 stars as this is likely going to be an indication of reliability/engineering/workmanship. It only took 6 weeks for a problem to develop which would normally be a good warning sign to replace during the winter months.
ULTRA HEATER
HEATING EXPERT
A new generation of aquarium heaters distinguished by their impact-resistant plastic housing and high-precision electronic thermostats.
The heater is easy to control using the ONE-TOUCH system that employs a single button surrounded by a ring of LEDs indicating the current and set temperatures.
The electronic thermostat operates with an exceptional precision (+/- 0.25° F) to maintain a constant temperature in the tank. This ensures that even the most sensitive of aquarium animals will stay comfortable at all times. Temperatures can be set in the range between 68 and 94 °F, which means that the heater can be used in treating
various fish diseases, including white spots. In addition, the ULTRA HEATER has a builtin system to prevent overheating of the tank water in hot weather.
Thanks to its unbreakable plastic housing, the ULTRA HEATER is ideal for use in tanks where large and strong fish or even water turtles are kept. At the same time, the heater is totally safe and does not cause burns in even the most sensitive animals, e.g. catfish or rays.

6 week update Feb 2, 2022
Descent heater so far Dec 19, 2021
After losing a clutch of clown eggs due to a failed heater I decided to go with this. Was a little hesitant because all the documentation I found on it said they were only celsius. Was pleasantly surprised to see mine arrived in fahrenheit. I didn't have to mess with the settings as it was set at 78. My tank was approximately 72 degrees from an underpowered heater so it immediately began working showing a blue dot at the current temperature and sequential flashing green at all degrees up to the set point until the set temperature was reached.
The instructions seemed next to useless, maybe 10 languages with the actual operations in the smallest font they could find, almost in something that would be used for legal disclaimer.
The holder is pretty flimsy, don't try to insert the suction cups in low light, you'll break it. The cups are keyed so you align and twist 90 degrees.
They don't actually state that it is submersible, but show a picture of it below the water line so there is a depth limit which seems to be different from industry standards. Mine is 4" below the surface and seems to be ok.
It's far from being as complex as the Helio and is much simpler to set the temperature than some with multiple rings on the top of the heaters. The only thing I'm not certain about is the temperature setting. Since it's a one-button show, I thing you have to continue to press the button until it circles all the way around to lower the set point. You'll also want to make sure you're at least partially submerged why trying to get to your set point if it's going to take more than 12 seconds.
All in all, this may be my new go-to for a medium-end heater, at least until it fails when I'll start looking elsewhere. Rating does not take into account reliability since this thing is new. I also didn't take off for the instructions since the operation is fairly instinctive due to the engineering design which went into the heater.
