Anyone use these? Super cheap on ebay. I know the cfs 500 was recommended in a recent thread so i got to wondering about these when i stumbled across them. I have mostly fluval heaters that i have not had any issues with so far.
I have a few Aquatop 300w heaters from Amazon, I believe they're the same thing (rebranded). Haven't had any problems with them so far. My oldest one is only a year old though.
