Best value for the money. It's very easy to install, i found that the stickiness comes apart after a couple of weeks, but i have the cords fixed so it dosent come up. I love the functionality of the display. I'm able to see my temperature and setting it up is very easy. Just click until the desired temperature and it'll slowly bring it up to temperature and stay that temperature. It's very durable, I've had it for 3 months and all is good.

Good value for the price although a little bigger than I expected, appeared smaller in the pictures. Easy to read screen, no noise operation, maintained temperature well without fluctuations, functional, appealing and durable.

This heater is great. I love the functionality of it, very easy to use. Very discrete, you can barely see it in my tank. It is currently in a 5-gallon tank with a single betta fish. It maintains the water perfectly within range with ease. sticks very well to the glass or plexy glass like in my case. looks very clean in my tank.

Got this as a replacement for an Aqueon that shorted out. It’s in a 5 gallon, but it’s bulky & a bit of an eyesore. Also, won’t stay stuck on the side of the tank and the cord is short.It works great so far. Consistent heating and the temp display is easy to read. Shipped super fast cuz I needed a new heater ASAP.

This has been idle for my sons 10 gallon fish tank. Durable, works well and let's me know when Temp has adjusted in the tank, usually only goes down by 2 or 3 degrees which is not bad. Value is great and has also been safe

I have 3 of these, each in a 10 gallon tank. They do not reach the set temperature. They are unable to heat past 72° degrees Fahrenheit in any of my tanks regardless of the set temperature.

Works well and fairly easy to use, sticks well and seems durable as nothing happened to it during a couple years use other than getting dirty.

El pez está muy agosto y lo noto más activo. Buena relación costo-calidad.

If I could give negative stars I would.I purchased this product at the beginning of Nov 2023 and now it's is mid March 2024.Within 4.5 months the display has broken leaving the first number visible and the second number half visible. (It was fine last night when I checked it)On top of this I have had this heater consistanly set to 74° with a thermometer in the tank reading between 72°-74° (this is in a 5 gal tank) Today I left for work as normal and came home to the temperature set at 74° although half the 4 is cut off due to the display breaking... The display read 77° I believe (again hard to verify with the broken display) and the thermometer in the tank is reading 79°.Thank god I came home when I did or I would have come home to a lot of cooked critters!! One of the shrimp is carrying eggs and I would have been devastated.This product is extremely unreliable. I am positive if I did not step in and unplug it when I did all the inhabitants of this tank would have met their demise.On top of all of this I cannot return the product anymore, and it only lasted 43 days longer than the return eligibility date.I do not recommend this product. It's size is very appealing for a small tank but it is not worth the risk. The amount of time and money spent on all the animals and plants in your tank is worth a reliable heater.
