Aqua Clear Heater For Small Tanks?

[gale]

Has anyone used this? It has good reviews but there are only 3. I know that jager or whatever are best but I have to buy two so I need something more economical. We keep our house at around 80 in the summer and 72-73 in the winter if that matters. I want something with an adjustable thermostat.

Thanks. I think I read that it isn't adjustable?
