Lakeland Large Free Standing Oven Thermometer 5 "Good to check" Marion 27 December 2018 My fan/ordinary oven has been playing me up terribly at the moment (new cooker on way I think!) as the preheat facility isn't working well and I can't always tell what temperature it has supposedly reached! Have found this little thermomenter a life-saver! No more over/undercooked mince pies! Happy Christmas cooking all!!
