I ordered the pyrometer to investigate my house for possible heat and cold bridges and insufficiently insulated points out. The first thermometer I had to return it, since neither the laser nor the display lighting functioned. At replacement of the laser device was not properly adjusted, so that the measuring point could not be targeted. But I think if you are caught without a device above shortcomings, you have a fairly accurate and very fast measuring IR thermometers at a good price.
