There are a lot of people with the Hydor models, including myself. I have mine inline with my inline CO2 reactor and no problems.

I like the Hydor inline heater. It's kept the water temperature perfectly stable for me. I plan on switching my other tanks to these as the current heaters fail or the Hydors go on sale.
