The eheim jagers are factory calibrated with an ambient temperature 24 degrees celcius. If your room temps vary from this then most likely you will need to adjust your preset temp reading to compensate.
I have been using these heaters for years both eheim and ebo and they both work fine. I think the glass is a little thicker on the ebo.
