Review on ISTA I H615 Inline External Heater by Elizabeth Carey

I had a hard time giving four stars because the thing is packaged in such a way that it spills out like a sieve. Not from the body, but from the connections. Make sure you have four zip ties for all connections. I would rate this product five stars if I didn't have to struggle to improve it. The idea is genius and I would pay more to keep the gear off my tank and off my landscape. In terms of accuracy, the thing seems to be worth the money. Celsius readings suck, but it only takes a second to convert Celsius to Fahrenheit on Google. If this thing performs better than the piece of junk I bought from Hydor I'll be very happy. I will post another review in the future to provide an update on performance.
