I have a Maverick ET-732 and an Isport (). All 3 read 211-212F in boiling water but the Maverick takes MUCH longer to finally read 211-212F. I have a MES 30 and they were all 20F within one another at one point (ee.g. 200F, 220F, and 240F). I was surprised they all read 212F in boiling water even though the Maverick took quick a while to finally read 212F. Is it normal for the Maverick to refresh so slow and take that long to finally read the correct temperature? It makes keeping stable temp. in the MES very difficult. Also, the MES is NOT accurate. It is shocking that it is soo inaccurate. For consistent 225-240F, I typically set it at 210-215F and have to crack the door even once in a while to drop the MES temp to force the heat on. Is this normal?
