I have two of these heaters (300w), they don't read the right temperature but hold it well. I checked the temperature with a highly accurate and calibrated Fluke temperature probe and the reading differs by about 4Β° from the actual reading. After setting the temperature correctly, they seem to hold the set temperature very well.
