The eheim was always so annoying as the temperature you set would never match the tank temp even after countless attempts at calibration. Also, the suction cups used on them are very very weak and begin to be less effective over time. In addition to this due to the design everytime you want to adjust the temp you must stick your hands in the tank and manually move the dial (and given the fact that I could never get the dial temp to match the actual tank temp it would produce, this was such a hassle)! I only wish I would have discovered these amazing heaters sooner. Stick it in, and then you have an external control unit that you set the temperature with with the touch of a button. Truly a beautiful thing. I purchased 2 of the 300W units for my new 75 gallon build (I know I could have purchased a higher wattage but I prefer 2 individual units in the event one fails there is still a backup and if it fails in the sense that one misreads temp and overheats, it is not powerful enough to overheat the tank). I have both of them mounted behind my 3d background next to each intake of my canister filters in opposite corners and it is performing FLAWLESSLY thus far. Much like every other Hygger aquarium product, this is of the upmost quality and I am such a huge fan. Review: Rock-Solid Heater I Trust in Multiple Tanks - These heaters work faithfully day in and day out. I’ve been running one in another tank for about two years now without a single issue, which is exactly why I bought this one for a new setup in a different room. Temperature has stayed stable and accurate, and the heater does its job quietly in the background, no swings, no surprises. My fish stay comfortable, active, and stress-free, which is really the whole point. Build quality feels solid, setup is straightforward, and once it’s dialed in, it just works. I don’t worry about it, and that’s the highest compliment I can give aquarium equipment. Reliable, consistent, and dependable enough that I came back for another one. ## Features - 🐠300 WATTS AQUARIUM HEATER - 300W aquarium heater is suitable for 40 to 80 gallon saltwater and freshwater aquariums.
