I actually experimented using a couple of thermometers. I set my oven to 220F and started keeping track of the temperature after about 15 minutes. The actual reading was from a low of around 225F to a high temperature of 255F. I should note that I have a super cheap oven and I kind of assume a higher-end unit would be able to maintain a temperature more accurately.
I would replace my oven, but I can’t. I’m living in a rental and the oven came with the apartment. So I’m looking for a device that is relatively small, that I can stow away easily when I don’t need it.
Something else you could try is the following—I've done it in the past to get a much more stable temperature.
Place a large covered roasting pan or stock pot in your current oven and test the average temperature inside that (keeping the sensor suspended)—it should be MUCH more stable.
