I'm really happy with this thermometer. Initially it was to check and adjust the temperature of my three freezers because with a contact thermometer that takes too long and if we constantly leave it, it fogs up so fast that we do not know how to read. Well it works and what a surprise to see the differences in temperature between the product and wall. As soon as the door is opened, the outside temperature of the drawer instantly goes to 0 ° see (because of the fog) while the products are at -18 ° C. But now that I have, I served every day to check my culinary preparations and in particular to melt chocolate or boiling water for pasta. One can also easily check the bath temperature, handy if you have a baby. I have the distinct impression that we have not finished to find applications. As for accuracy, hard to say. In any case it was a very good estimate. For the measurement to be accurate it should be taken at 36 cm from the object, the reflective or transparent surfaces are a bad influence on accuracy. The use of lazer (optional) improves thereof. If possible, we can always do a comparative measurement with a conventional thermometer. But against part is super fast and very easy to use. The instructions received is in German but the company sent me the French version of eMail, do not hesitate to ask if needed. Even with the battery size 9V buttons in the handle, the unit is lightweight. The plastic coating is very soft, it gives a feeling of warmth and is not messy. My only regret, color (I have the impression of working at Caterpillar). Green or fuchsia, he would not have denoted in my kitchen.
