  • Waste of money and can crash your tank By Kotler's Reef on 7/17/2017

    Bought this in the spring and did not use it till November. Probe failed after 3 months. The controller was reading the temp 10 degrees higher then it was. I noticed this bc I have another thermometer. Called JBJ the told me that I need to replace the probe every 3 months. If this was disclosed at time of purchase I would never buy this. I'm now getting and APEX. You should save your money on this. Considering the an APEX jr is not that much more and will not fail like this.

    I've had 2 of these fail within just a few months of use, luckily they failed in the off mode.
  • you get what you pay for, usually By Raymond on 2/27/2017

    It works so far, but, the front control pad is coming off 'de-laminating' in less than two weeks of use
  • No emergency auto shut off. By Jason Bianchi on 1/26/2017

    Thermostat came out of tank and read the house temperature and ran for 11 hours straight. Would of liked to see an auto shut off after a certain amount of time with no temperature fluctuation in the reading to avoid cooking the tank. However when the probe is in the tank I can hold a two degree tolerance with a Finnex titanium heating element in a 29G biocube.
  • would recommend this By bwatt on 1/9/2017

    I have had this controller on my 2 tanks for three years with no problems. Had to replace one heater after about a year and a half
  • Would not recommend this product By Floyd on 12/7/2016

    Bought this item and did not need to use it right away, finally completed build on new tank plugged in controller.....nothing. Not working right out the box, of course it was out of warranty. called JBJ explained the situation, they refuse any compensation, no help what so ever offered. Would not recommend this product.Gave it a star cause i had to.
  • So far so good By RogerAGrimes on 12/5/2016

    Only had mine a week, but so far it's working great. I have a total of three temperature sensors, and it's tracking as accurately as the others (so far).
  • Buy one By Mark on 3/13/2016

    Was really tired of adjusting my heaters , set up the controller worked great. Make sure u call to tank temp,
  • Meh By Cave Man on 3/7/2016

    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 Dan 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.
  • 1 year in By Ray on 1/18/2014

    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.

  • Garbage By Richard on 11/23/2013

    Had 2 of them and both failed within a year. Poorly made, both of the temperature controllers would not read any temps.
