It is cheap and might be useful to some people. Definitely useful in restaurant business environment but I needed this thing in my home too. Recently my freezer started misbehaving and instead of using an infrared thermometer I could really use this thing as I didnt have anything better at the moment. What you set on your fridge is not always what it holds inside, it’s a good way to check on temps.
