The disagreement is real and worth weighing. On high-trust r/Aquariums, one owner described using free Orlushy units only to have them "fail within a couple years" before switching to Eheim Jagers, and another noted the small versions aren't programmable and hover around a fixed temperature. So the picture is a powerful, cheap, widely-bought heater that some owners trust for years and others find short-lived.
The synthesis: as a budget workhorse the Orlushy earns its place on sheer adoption and heating capacity, but it isn't the pick if you want long-term peace of mind without a controller. As one r/Aquariums commenter wisely advised, don't over-weight isolated one-star reviews when sentiment is broadly positive, but do plan for eventual replacement.
- Orlushy aquarium heaters come in six different sizes, suitable for small fish tanks, aquariums and turtle tanks. Please choose the right wattage aquarium heater according to our size chart.
- Stable Heating
- Stair shape heating that red light is on and heater starts to intermittently heat the water to the set temp, saving energy and electricity. When green light is on, heater stops working and maintains the temperature constantly. It also come with a separate thermometer for real-time monitoring of the aquarium water temperature.
- Durable & Material
- The durable material of the heater ensures safe operation. The outer shell covering the whole body of the heater is made of heat-resistant ABS material that it won’t deform and melt under high temperature. The heating rod is made of nickel-chromium heating wire to faster heating rate, and non-corrosive quartz glass.
- Cautions
- 1.Please ensure the heater is 100% submerged into the water before plug in the power. 2. Please unplug the power and cool down the heater for 10-20 minutes before taking it out to clean the fish tanks or change the water.

I would use them (cause they were free) and then they would fail within a couple years and would be replaced with Jagers.
I use an Orlushy heater for my 5 gallon hospital tank but like most small heaters, it isn't programmable and stays around 78F. Something like ...
