  • So Let Down By Aaron on 7/8/2014

    The heater exploded in my sump. All the fish are dead. All the shrimp are dead. The coral looks very bad.

    I have never felt so let down my a product.
  • like the flat design (150) By shawn on 7/1/2014

    Keeps temp in my Nuvo 38 gal within 1degree of setting. Nice flat design with snap in suction mount. Working well and would recomend.
  • Love this heater By Lionel on 4/10/2014

    Although the cost is slightly higher than other models, after having 4 glass heaters fail on me within the first 6 months, there is good value with a 3 year warranty.
    Also nice to have a heater that has the indicator and sleek design
  • So far works great By Ryan on 4/7/2014

    Have only been using it for 1 week but the product has been working as advertised. Currently using the heater to heat a tub to cook rock in m,y garage and the temp has bee really steady even in the morning when it's pretty cold.
  • Busted within 2 months of purchase By Kailua-Kona on 3/24/2014

    The 200W Neo-Therm is a great product when it's working. The plastic shell busted within 2 months of service and now the heating element is dead.

    I have tried to contact Cobalt customer service, but I am still waiting for a reply.

  • These are very solid units!! By Sean on 3/19/2014

    Cobalt has done a fantastic job with these heaters. I got two 200W units and am very impressed with how solid they are built. The only thing I could ask for would be better suction cups that hold them to the inside of your sump or tank.
  • Great product! By Luis on 2/24/2014

    Great product! My temperature used to swing +-1 degree with my old heater. Ever since I put my new neo therm heater in my swings dropped to +-0.2 degree. Very accurate, indestructible, small footprint and easy to read thermometer.
  • Leaks Voltage By Worm5406 on 1/21/2014

    I bought 4x 200 watt versions of these. I have now had 2 of them die and leak voltage into the tank. They not only leak voltage they both would not light their own lights and even show they were on. I took a voltage meter and tested it numerous times, and replaced it and the 90VAC in the tank disappeared. I would understand one... but two within a week time span in unacceptable.


    I have had one get a thermal barrier around it in bubbles and stop heating.

    I do NOT think these are what they are cracked up to be. I had high hopes for them but with 50% failure, I am sure I will be sending them all back and switching to the old standby, glass... Even though I do not wan to, I can not stand being shocked.

    After I left the two bad ones outside the tank they turned back on and stop leaking voltage.
  • Great product By jarodw45 on 1/13/2014

    100 watt heater works quickly and keeps water temp perfectly Set at your desired set temp.
  • Very happy! By Leslie on 12/20/2013

    I am very happy with this heater! Easy to set up and I like that it shows if the temp of the tank is above/below the desired set temp. As always,great service from bulkreef!
