Customers say
Customers find the aquarium heater works well, particularly for 5 and 10-gallon tanks, and appreciate its compact size and good value for money. The temperature control receives mixed feedback – while some say it consistently maintains the set temperature, others report it doesn’t reach the desired setting. Moreover, durability is a concern as multiple customers report units burning out within two weeks. The heat level also gets mixed reviews, with some saying it heats well while others find it inadequate.

I own three
Awesome little heaters! Work great for 1, 5 and 10g tanks! Temp isn’t super steady in 5 and 10 g but it keeps within a few degrees. Easy to use.

Highly recommend
Great heater. Love the digital display on the cord with the control button!! It tells you the actual temperature of the water at all times!! Heats as high as 96°F. Very reliable so far! Also supposed to go back to setting if there’s a power loss! Is recommend for complete submersion but that means you can put it on the floor of your tank if you preferred. My Betta loves to hang out by it sometimes. Hasn’t damaged my live plants that won’t stay in the gravel and end up floating around it constantly.

Got the 5-15 gallon heater for my 2.5 gallon tank.
Out of all the incompetent aquatic heaters, popular brands at that, this heater has always been a reliable one. I have purchased two of them, one for a 20 gallon and another for a 2.5 gallon tank. I would recommend ordering a size up, as ordering smaller will probably not heat as well. (I have the 5-15 gallon heater for my 2.5 gallon and it is the perfect temperature). The size of the heater, despite ordering a bigger size, is perfectly small and compact yet it still works great. However, it can be very fragile. Be careful while doing tank maintenance, always turn it off when it’s out of the water, and make sure it is fully submerged in the water. A great heater for the price nonetheless!

WORKS GREAT!
I was skeptical because the only aquarium heater I ever trusted and found that works good was a good old fashion traditional glass, electric internal element and boring dial heater. After reading reviews I tried this one to use in my 100 gallon pond which has my small Koi and lemon plecos in it. I like to keep them cozy during winter plus I have lemon plecos in there too who keep the pond very clean, this set up works well in North Florida. We can get a few 40 degree days/weeks in winter but this sand heater helped keep the water at 68 degrees during those days/weeks. I could put another 200 or 300 watt in to reach 78 degrees for the lemon plecos when it’s 40 degrees outside but it’s unnecessary. Everyone does fine at 68 for a short time.The built in thermometer works pretty good too. The sand in the glass is an unusual way to heat and I didn’t know what to expect. It is working very well and consistent in the auto on and off at temp setting you prefer to set. I got 2 of these 300 watt’s one is in a 75 gallon aquarium and the other is in 100 gallon pond outdoors.As small as it looks it gives a big and quick heat up at your chosen setting. I was surprised how well it works and fast.The only thing I am being careful about and worry is the digital external compartment that’s built into the cord gets very warm and I don’t know if it is water resistant or not or that if it could catch fire being this compartment gets so warm/hot when heating is on. So my advice is be careful where you place that external piece. Maybe hang it and cord off the aquarium rack somehow or something so it doesn’t get wet and be sure that compartment is not up against any carpet, wood or Sheetrock walls, always think SAFETY FIRST when it comes to aquariums and where to place things.

Button sticks but strong heater
I ordered two of these. I love the slim look and the LED remote. I like the first one so much I ordered a 2nd one for my other aquarium. They both do a great job at heating the aquariums. One is a 54 gallon and the other is a tall about 40 gallon.The BadThe included thermometer did not work at all and I had to scrape it off my aquarium. The button on my 2nd one gets stuck. I have had to play around with it to get it to stay on F and to stay on the temp I need. Everytime I go to make a change I have to hold down on the led area and then press the button and then make sure it is not held down. The first one does not have this issue.If I need another heater I will likely look for a different brand.FYI if it gets set to C you have to hold the button down for over 10 sec but it will switch over. Or you have to do the conversion to see what it is set to.Update: Seller has reached out to me and we have resolved the issue. Adding stars for great customer service and reaching out to me.

Keep a close eye on your temp with a separate thermometer!
At first it was great! It quickly brought my 39 gallon hex tank to temperature without issue. Occasionally, it seemed like the temperature in the tank wasn’t what the thermostat was set at but it was never anything overly concerning. Today I noticed I suddenly had four dead fish floating in there and the others looked very distressed. I checked the temperature using the separate probe I had installed and another one to confirm it wasn’t faulty measuring equipment – the water was 94.2 degrees when it was set at 73! I’m very upset and unsatisfied. So much work goes into establishing these environments then a malfunctioning piece of equipment that was used for less than 5 months suddenly put it all in jeopardy.
