No matter the reviews on a product, for me, the product is as only as good when it functions properly for me. If the product fails on me, depending on the type of product, I am reluctant to purchase that same product a second time.
I just watched the Secret History Living video of the catastrophic failure of the heaters he had and what he invested in the tank that failed. I am unaware of Aqueon's response to that. That was a crying shame.
The only heaters that I have seen recommended in two of my LFS are the Aqueon and Ehiems. Yet, Aqueon has a less then stellar approval (especially Secret History) and one LFS had 17 Ehiems fail on them. Yet, the LFS still purchased Ehiem for replacements.
I have one Aqueon but not the "Pro" that split. I don't have an opinion on it, yet because of Aqueons reputation on their heaters - I don't trust it, so it sits in a box as a last resort.
I have the Ehiems since day one when I was thrown into the hobby (1 1/2yrs now) and no issues. I don't care for the calibration method.
One of the LFS came back from the Dallas show and now carries the Polish brand Aquael. I'm going to try their heaters.
And yes, I do have the Co-op heater but I have issues with it. I'm waiting for version two.
The quest continues for a reliable heater.
P.s. I really liked Atitagain's advertisement. 😉
