hygger ECO Fish Tank Heater Explosion-Proof Stainless Steel 500W Aquarium Hea...

I have a 265 Gallon Aquarium, My old style glass tube heaters burned and killed a few of my expensive fish. They had gotten bigger and found out that they were leaning against the heater and burned them which later cause me serious issues with my tank from their injuries. I researched aquarium heaters and and because of their design to shield the heating element from fish I decided to try the new product that did not have any reviews. I ordered only one heater first to give it a try. I received it through AMAZON with no issues. I read the instructions and installed it on one side of my tank. Turned it on and the heater itself worked great but it only came with one dual suction cup retainer to keep it away from the glass. Because of the size and weight of this heater the one suction cup did not work well and the heater no matter what I did, did not want to stay off the glass. Well I looked at the instruction sheet and there was an email that if you have any issues to email them. Well I emailed Hygger and explained to them that my issue with needing another set of suction cups that is needed to keep the heater off the glass. To my pleasant surprise I received a response email with acknowledgement of the problem and advised that they confirmed the problem and advised me they would send me another set of suction cups. I did receive the second set and it resolved that issue. That heater is working great with no issues and easy to read LED display. HOW, I ordered a second one because of the size of my tank. The second one arrived and I installed it. Three days later the outside LED went out. Figured maybe just a defect and immediately returned it to AMAZON which they immediately sent me another one per my request. Well the second one did the same thing, returned it for another one, third one did the same thing, outside LED went out. I again emailed Hypper and again received a response which the advised me that that did have an issue with a certain run of heaters but they have now resolved the LED failure issue. Well I received my fourth one from AMAZON and it is working perfectly. Although I had at first on going issues, Hypper customer service was outstanding and the heaters are working great. So they get a 5 star from me. FYI I also have a air pump from Hypper and it is one of the best I have had and works great in the 265 gallon aquarium. In closing if you have an issue EMAIL THEM, Hypper will go above and beyond to resolve your issue.

I bought this heater for my 180 gallon take back in December 2020. The item was packaged nicely and arrived in good condition. The built-in display on the actual heater is very useful. It also has a controller that I attached to the side of the tank to make adjustments as needed. After three months, the unit suddenly stopped working (constant beeping with "Er" code flashing). I unplugged the device for an hour, but still had the same issue. I decided to email Hygger's support and to their credit, they replied back within a few hours, asked for some pictures of the heater and proof pf purchase, then ensured me they would do their best to help me out. Two days later I had a brand new replacement waiting for me at my door step. Hoping this unit does not flake out on me like the first one, but at least I am confident now that Hygger will provide a quick resoltution.

Running-dry protection, auto shut off when removed from the water, and resume functioning upon return Shatterproof titanium tube construct, heating fast and(************** corrosion resistant***************) ABS plastic protective case prevents fish from punching and scald External digital controller can easily be adjusted temperature without getting your hands wet Easy to read white LED digital number display shows current water temperature Adjustable heat setting from 68°F to 93°F (20°C ~ 34°C), electronic thermostat accurate to +/- 1 degrees Fahrenheit differences Ideal for used in 60-180 gal freshwater and saltwater aquariums The product that I received and ordered was based on the features above specially**** corrosion resistant*** but after a month of use 2 heaters started to corrode. I bought 6 of hygger heaters on Feb 10 and the return window was closed on march 12 with amazon. Praying my other 4 don't corrode. I have enjoyed other Hygger products that I have purchased in the past but i also want good value for my money specially for my commercial business. Unless hygger replaces these items i definitely don't recommended them specially since they advertise corrosion resistant.

I’ve used this for my turtle tank. This heater works better than any other water heater I’ve ever used. I like the fact that it has two digital reading outs. He’s in a 75 gallon tank and no his tank temp is not always that he just got his tank cleaned and the temp is regulating to his normal temperature which is 72. we’ve had this heater for about almost a year still works great definitely recommend for anyone who has a turtle or freshwater fish would not recommend for salt water tanks

So I have bought a total of 3 heaters frog hygger. I bought all 3 off Amazon. I heard good things so I bought the first one and I died in a few days, my bad I didn’t read the fine print “ fresh water only” it worked awesome until it didn’t anymore. We ordered heater #2 made sure it was for “salt water” . So if you buy a hygger heater for salt water read the description carefully and make sure it says it is for saltwater. That is the best heater I have owned. Now for the reason I’m am giving only 1 star, heater #3 the unit looks great boxed and package is nice, read the instructions ( not the best) put it in the tank, let it sit 30 min or so and plugged it in set the temp, and it brought the temp up but 2-3 degrees low so I did the math and set it accordingly. Went back a few hours later the display was blank, thought maybe a sleep mode but only 1 button, and it did not wake it up. I called the 1 -800 number and was told to contact him on Facebook so I had my son contact them on Facebook with the pictures they requested. 5 day’s now no reply, giving this review a try to get attention. I just want a working heater! While on the phone the guy said I must have on of the fits ones and they do have the display issue. 12/30/20 update Today I got my replacement heater. Hope this one works! I will update in a few days 1/4/2021 update Running for a few days now works perfect. Changing rating to 4 stars because I had to write this review to get help.

it has remote heating portion, and then the controls show the actual temperature. It shows if it is heating and has an eco mode to save power. This is my third one, the first two lasted 3 years, witch is good compared to others.

I got this for a sump system on a 125 gallon freshwater setup. It's easy to set. I always unplug it during water changes as no one should ever rely on the auto shut off. I feel most reviews that the heater melted were running it partially submerged. I would buy this exact one if mine quits

Didn't even last a year. But when it did work it worked great. But they contacted me and sent me a new one even tho I was out of the return window good customer service.
