Don't feel singled out, as it is a problem that most heaters have, not just Jager. I highly recommend a temperature controller to ensure better accuracy and as an extra failsafe (since the internal thermostat is not usually very reliable). This will save you headaches in the future and potentially save your entire tank. Once you've had a heater nuke your tank, it is hard to put faith in them, otherwise.
As far as controllers go, I highly recommend Ranco controllers. There is a bare, unwired version and a pre-wired version. They are easy to wire with the included diagram, but both options are available.

Someone locally just today had a heater fail... causing this to his small pico tank. 4 year old heaters are not wise to use. 
As far as the question, I use a digital thermometer to check the temp of the water. I never rely on what the heater is set to, it is always wrong, and more often wrong in the warmer direction, ie. 78 on the dial = 82 in the tank. I agree with Amphiprion though, for the safest method to control a heater I always hear the Ranco controllers are the absolute best for that purpose.

The replies did make me feel a lot better. I just can't seem to get the temperature below 80. Now it's set to 77 and its heating to 80 even after playing around with them for nearly an hour. Anyways for now I'm going to buy another thermometer to make sure the current one I have is accurate and adjust the heaters using the thermometers.
You can't play around with a heater for an hour.
Make a change and check the status after an hour, maybe. Better yet, the next day.

They only heaters I will ever use are the Catalina Externally Controlled Titanium Heaters. The controller is on the plug, not the heater and I have never had one fail. They are more than the others but you get what you pay for..
Unless you can find them cheap on Ebay
