Jam Making Preserving Pan Kitchen Thermometer 5 "Disappointing" Mrs Grossman 24 June 2018 This is my second Lakeland jam thermometer, I returned the first because it reaches what appears to be 100-102 degrees and will go no higher no matter how long the jam is boiling. Like other reviewers, I find it difficult to read. This second thermometer is exactly the same as the first. UPDATE. While l did have issues with this product, the speedy, efficient, helpful responses from Lakeland, have been excellent. I wish they could run classes for many other companies on how to treat customers! I am very happy with the outcome and will now rate the whole experience 5 star. A note from the team Many thanks for your kind review. We're glad we were able to help.
