Underwriters Laboratory dedicates its organization to guaranteeing products meet stringent safety standards. Smoke detectors, extension cords and many products in between have a UL sticker. This means that the manufacturing facility and the device passed the inspection. Now, some manufacturers try to bypass the inspection by creating fake UL labels.
If you buy a device, make sure that you check the sticker. Look for typos or any differences between that sticker and one you know to be real. If a company avoids a UL inspection, it usually means that the product won’t meet basic standards. Don’t trust that type of appliance in your home.
