  • Buy one By on 3/13/2016

    Was really tired of adjusting my heaters , set up the controller worked great. Make sure u call to tank temp,

    It was awesome for a while. But they should tell you that you will need to replace the probe every year. Spend the extra money for an Apex controller instead!
  • Poor quality produtct. By on 10/13/2014

    Accidentally drop it from like 1' and It died. I've opened it up and find out that transformer on the PCB popped out! What a joke how loose soldering should be to let it fall out of it's place? Skip this product.

    The probe went bad. I was basing my temperature only from the digital display. I noticed increase algae and corals where starting to close/die. then noticed increased evaporation. purchased a basic mercury thermometer an found I was running at about 87.5 - 88 degrees and my display said 78-79. I contacted JBJ and they said they have seen this problem multiple times and they were willing to sell me a new probe for around $20 plus shipping.

    This could have been avoided if I calibrated my heater before connecting to the JBJ. Which if you purchase this product I strongly recommend to calibrate your heater to prevent overheating.

    Currently I am running and Ehiem jager which is seem bullet proof so far but I plan on purchasing an APEX Neptune redundancy.

    Had 2 of them and both failed within a year. Poorly made, both of the temperature controllers would not read any temps.
  • Worst Company By on 6/18/2013

    I bought this heater, had it stick on and I caught it before it overheated the system. The probe was faulty so I replaced it with a brand new JBJ probe. Less than 3 month later the probe goes out and the tank is at 92+ degrees Fahrenheit, killing countless SPS. Wrote an email to the company and no response. Beware JBJ products.

    Had mine for about 8 months, then the Er message kicked on and the heaters never came on. Luckily my OCD kicked in and found the water temp around 74*, before it got too low and killed the reef/fish.
  • Great Product By on 4/25/2013

    The controller does the trick. This time of year one day with A/C on and the nexted the heater kicks on. So far this unit has adjusted well except the 2 degree tempture swing.
  • Not good By on 2/10/2013

    My friend and I both bought one of these and both went out quickly. Mine said 45 degrees making the heater never turn off. Came home to 100 degree tank and 14 dead fish !!! DO NOT BUY THIS GARBAGE!
  • failed twice in 5 months By on 4/11/2012

    I bought this at Christmas but the controller arrived broken so JBJ agreed to replace it. 5 months later, I came home and the controller registed my temp at 0 degrees regardless of the actual temp, stuck the heater on, and killed my established reef that I've kept for 8 years. Never trust this controller
