I have a bunch of tronics and one ebo jager heater. Neither has failed me yet, and I haven't heard of anything bad about any of the heaters. However, if given a choice, I'd probably go with the tronics. I like how the tronic heaters are smaller than the ebo jagers.
Our tronics will only go on if the water gets below 73 F. even though they are set at 81 F. With our ebo jagers they went out after about 2 years of use. I wonder if it’s something with our aquarium? Maybe some stray voltage?
