Review on Anvin Oven Thermometers: Large Dial Grill Monitoring Cooking Thermometer - Dual Scale 50-300°C/100-600°F for BBQ Baking - Durable Steel - Pack of 2 by Greta Jobin

This is a great price, but obviously not worth it if it's inaccurate (or even close). I tested one in my toaster and then both in my regular oven. They were about 50 degrees below the actual temperature each time. My old oven thermometer was getting harder to read so I bought these. I know my regular oven gets 15 degrees hotter than normal, so I'm adjusting to that. I suspect it might be a quality control issue as there are a number of satisfied customers. Regardless, they just weren't right for me.
