A terrible attitude - they sold an obviously faulty thermometer (all 4 people showed 37.3, although only the child was ill and his temperature was questionable - that's why they bought it). I explained - to which they replied - well, mercury is filled in hot water🤦♀️🤦♀️🤦♀️ And the fact that it is uncalibrated does not matter. I offered the pharmacist to check on myself - I refused. I changed it to exactly the same one, most likely also with a marriage with words - you most likely just leave, so you decided to return it🙈🙈🙈
