Cob Heater Neo-Therm Led 100w

Super steady temp, it might not be perfectly on the set temp but it is close enough and it holds it there perfectly steady! I love this heater.. it’s not cheap tho

Excellent !!

GO BUY ANOTHER BRAND BUT NOT THISI have three tank and did use 4 to 5 of those thermal heater at different wattage, all stopped working or malfunction, the last one I had really pissed me of because one day I left my house last 1pm and I did see just before, the temp was set to 78 and showed green led, returned home around 8pm and noticed all my fish fried and dead, because the water temp was 100+ and red led was showing on the heater. I emailed them and contacted them on their site and 2 weeks later still not response.I am immediately took my other heaters from cobalt from the tank and beat it hard on road to release my anger and threw in the garbage.
