Accurate and easy to use heater
Very easy to set and read the desired temperature, and it seems to work more accurately in low-flow aquaria than, for example, Fluval e-series heaters.It isn't a 5 star product as I have had a few of these fail on me over the past decade of use. Honestly, though, it doesn't seem a worse product than the competitors for this. I wish manufacturers could make something reliable in the long-term at a reasonable price point.Tip: use 2 heaters, each rated slightly below the recommended wattage for your tank. A failure in one won't wipe out your tank before you have a chance to notice something is wrong. Unfortunately difficult to do in small tanks...

Looks to be a good quality heater
Looks to be a good quality heater. I would recommend it over some of the cheaper ones, especially with the 5 year guarantee.
