Query: WHERE'S THE HEAT?

Based on recommendations on Amazon I bought this deep fryer. Tried it out right away. Canola oil to maximum line. After 30 minutes the oil only reached 325 degrees F by candy thermometer that reads 210 in boiling water. All recipes call for temps of 350 or 375 degrees F. I wish someone made a deep fryer that tells you the exact temperature of the oil and gives you the freedom to raise or lower it as you add food or want to cool it down for something else. Sent it back.
