I kinda went down a rabbit hole a few months ago on heaters. Wanted to try out the new IM Helio PTC heater as that is the newest tech, but I'm definitely not one to adopt new tech in something as important as a heater as I read a lot of negative reviews that gave me an uneasy feeling. Finnex titanium and ehiem are always the old go to, but after reading and talking with a buddy in Italy who breeds discus I went with the BRS heaters. They are made by Schego and are great Germany made heaters. I like the fact they seem to pull less amperage than Finnex heaters per watt which is important on bigger wattage heaters. I've had the 600w one for 3 years and clean it twice a year and it has been rock solid. I have a spare in the closet for the day it dies or acts up. Just my thoughts on the topic. I'd love to hear some local successful stories on the PTC heaters. Aaron Sent from my SM-N975U using Tapatalk
