The heater I bought originally worked great until the temperature reading started going through the roof, eventually hitting 93 degrees. After I contacted Hygger about the inaccurate readings, they sent me a new heater free of charge which works great.Would definitely recommend the product, it’s convenient and easy to set up. Originally my review was poor but after they sent me a new heater despite me not asking for one I moved up the rating to a 5.

The media could not be loaded.First impression unboxing – while the heating element & housing are compact, the unit as a whole is bulky & seems somewhat cumbersome. Partially true in practice, but so far, I’m extremely happy both by its performance & aesthetics.The initial set-up is more than a little tedious, & instructions aren’t the best, but w/ minimal effort, the unit can be installed unobtrusively & only minimally affect overall aesthetic of the tank (see video). The cord from the heating unit to the controller is the biggest challengeIt heated my 28 gal by 1 degree in under an hour; good enough performance for me.After about 6 weeks of light use, the heater has kept a constant reading of 79, which is 1.5 degrees off from the 77.5 I get according to a calibrated digital thermometer I trust. Not really a problem for my purposes; as long as it’s a consistent error, I can deal, & it stayed consistent thru’ several temperature adjustments.I have minor concern about the controller; it seems almost flimsy compared to the sturdy construction of the heating element/housing. Maybe b/c it’s plastic while the housing is of other material? Maybe b/c it IS flimsy? I had an issue w/ it not responding when trying to adjust temp & suspected bad wiring job, but power off re-boot solved it.Overall, I’d recommend this heater if size is a big consideration, which it was for me. The parts in the tank are much smaller than most competitors. Also, even if size isn’t a concern, it’s worth noting that keeping bulk of the electronic components out of the water should help prolong expected lifespan.To sum up – it’s worked well for me so far & I like it a LOT better than the bulky, traditional all-one-piece top sticking out of the water hard to adjust unit it replaced.

I’ve only had this heater for a few months and I love the performance. I have a 60 gal that I keep at 81, discus .It keeps a steady temp and rarely varies beyond .5 degrees. My only complaint is the hardware. The suction cups are junk. I’ve had a few incidents where the temp prob came loose and tripped a separate temp alarm. The cups on the contoler fail allowing it to fall pulling the temp prob down. It is a fair amount of weight. Could be a real problem depending on how you have your wires run. Other wise great little unit.Seller contacted me about my review. They promptly sent new hardware. I’ll give it a test and update my review as needed.9/18/23. New suction cups failed. Yes the surface was clean. I scraped both surfaces (outside for control unit, inside for thermometer) they held for a while but i came home today to a 91 degree tank. Luckily I got a water change in to get it back down and no fish loss. I really like this heater but the suction cups need to be re-engineered. If i had this tank stocked with discus as planned, I could have been out hundreds of dollars in fish
