  1. Poor Thermometer

    By Mark Hinchcliffe 12-11-2014

    Having purchased two of these thermometers from here, was most disappointed. Has mentioned previously, they were not like the ones pictured. They gave different readings on the same thermometer for high and low. And on one of them the red coloured faded away. On both of them they kept getting air bubbles and when I tried to warm one up a bit the glass broke and spread some nasty smelling oil out of it. I would urge Thomson and Morgan to stop selling these rubbish thermometers. AVOID.


    Thank you for your review. I am very sorry to hear of your disappointment with your recent purchase. I have passed your comments on to ensure this matter is investigated further.

  2. Buyer Beware!

    By Ross Meredith 18-01-2011

    Buyer be aware. Thompson & Morgan did not supply me with thie rather nice looking red / aluminium thermometer pictured. I ordered one which arrived today. I was disapointed thet the model illustrated on the web site had been replaced with a cheap and tacky looking substitute which I could have purchased locally for a fraction of the price. Dissapointed indeed.
