This review is from: Black & Decker TLD100 Thermal Leak Detector (DIY & Tools)
Fairly good product really lets you see temperature variations around different parts of the home.ie windows and doors.You will also see the difference a blind or a curtain can make about 5 degree difference. You can also find places you may need to silicone to make a better seal and cut out drafts etc.Also it comes with its own batteries so you can use straight away.
