  • First one worked perfect, seller gave me full refund for second which didn’t work
Size: 50 Watts
I’m changing my review to a 5.0 because the one heater that didn’t work the seller contacted me and gave me a full refund without having to send it back, and then I ordered another and this works perfectly also. I bought three of these total. The first time I bought it, it worked well, the temperature always accurate within about a degree of what the product reported on the thermometer, and it keeps my tank heated well. So I bought another for my new aquarium. The second one did not work. The thermometer would say 83 when the temp was 78 and it wouldn’t heat the tank when the temperature in my room got colder. But after I reported this second one not working the seller contacted me and offered a full refund without sending it back. So then I purchased another to replace that one and the new heater again works well like the first, the temp is accurate so far and heater working well! The first one I purchased I’ve had for a few months now and not had any issues so far. ... show more

  • Works awesome
Size: 25 Watts
great value for the money. Tells you the ambient temp and you select the temp you want and it keeps it there. I'm using this in a 7.1 gallon tank

This small heater fits perfectly in my Fluval Flex V aquarium filter box next to my uplift tube. I heats the water adequatly. But the thermometer is off by a few degrees. I try to keep the temp at 75-76 so I still need some adjustments on the settings. So far so good. Yes, I do recommend this to others. Mark ... show more

  • Did not work 😞
Size: 25 Watts
The media could not be loaded. This had great reviews so I bought 2 for 2 small palladium’s with 5-7 gallons of water each. I loved the digital control which makes it easy to check your temperature anytime at a glance. It took me much longer to complete the first palladium than I thought. I am 12 days past the 30 day return 😢 I got my tank completed, planted & hooked up the heater. The lights on the controller worked & appeared to set the desired temperature, however it never heated the water. I kept thinking that I was doing something wrong or maybe it was the AC vent near by so I have spent the past 4 days covering the AC vent re-reading the instructions & trying to reset it still thinking it was me. Finally I got my husband involved & he had the same problems. I reached down & touched the heater & it was stone cold. It must be a heating element or something. It even reads the current water temperature correctly because I tested that with an aquarium thermometer. I am just sick it don’t work. I have already ordered my vampire crabs & they will be delivered next week. I really loved this heater & wished it had of worked or that I could get another one. I will try the second heater & report back to let everyone know if it works or not. I understand things happen & it could just be a one time thing. I included a video of the unboxing, it was packaged very well. Also a photo of one of the many test I did trying to make sure I wasn’t making a mistake & finally my palladium I built for vampire crabs. My only hope is that the second heater works & maybe this company will see fit to replace the broke one. I will gladly change my review to 5 if I can get a replacement. Thanks So no update I accidentally broke the second heater, I dropped it. I did take photos of the 2 side by side. The one with orange wires is the one I worked with. The second one with gray wires looks like it was hooked up different, I think the first one was probably defective. Now I have to rush & buy yet another 2 heaters….. ... show more

  • fragile
Size: 50 Watts
UPDATE: Customer service reached out and was very kind and helpful! Still be careful not to brake it! It is a great size. Unfortunately I only got to use it for one day. The 24 hours it was in use were good. Temp. was stable and accurate. The suction cup kept un-suctioning causing the heater to fall into the sand. so this morning cleaned that area of the tank very well and tried to make sure the suction got a really good grip. Since the heater was plugged in I merely detached it from the suction gripper thing and left it in the water whilst I worked with the suction cup. I thought a good suction was achieved, slid it into place and went to put the heater part in its place. This is where my soul was crushed. Popped the little heater back in, and it taped the back of my aquarium glass causing the glass on the heater to break. I immediately unplugged and went to remove the heater. The tip came all apart. This released the black glittery sand that is all inside. UHHGGGHHH this is such a pain to clean up. It doesn't seem to be bothering the fish (hopefully it really is just sand) but it is everywhere! Cleaned it up the best I could, but its impossible to get it all. I feel as if i was glitter bombed. Now I'm out a heater, out the like $18 (don't feel right asking for a refund since it was my fault ) and spent a morning doing extra water changes. grr. However if you are VERY careful i think you can still enjoy this heater. ... show more

  • Really nice heater on the second go round
Size: 25 Watts
I liked the adjust ability and digital temp display on this nano tank heater. The first one just wouldn't settle properly on the desired temp and was 6 degrees high on the display. I returned it and got the new one with no problem....Thanks to Amazon's wonderful business practices. This heater is right on the temp and works the way I had hoped. My old heater still worked but the temp is not adjustable and I needed one to push up to 80 degrees f for tank cycling/bacteria growth. This heater does that job to a tee. And the display is very nice feature now that it's accurate. ... show more
