Query: Oxo Good Grips Oven Thermometer

My gas oven (new to me) wasn't getting to the proper temperature so baking was not satisfactory. When I put in the Oxo thermometer and set the oven to heat to 350, it was only at 200 when the oven signaled that it was up to temperature. When I set the oven timer for 20 minutes, it was up to temperature and baking was then just fine. The thermometer made all the difference in success for me.
