1.Can I use it to measure body temperature?
- We do not agree with this usage. Because the sweat and body oil will affect the reading, the data is not accurate. You'd better get a clinical thermometer if you want to take the temperature of people or animals.
2.Does this unit have an auto shut off feature?
- Yes, it does. It will turn off automatically after 12 seconds.
3.How far is the effective range?
- Actually printed on this device is the ratio between the distance from the object and the diameter of the spot being measured, which is 12 : 1. That means if you're standing 12 feet from a wall, the area that you're measuring is a one-foot ( diameter ) circle on the wall. If you want to measure a one- inch spot, you need to be within 12 inches of the object.
4.Will it measure the temperature of a room?
- It can measure the temperature of objects in the room, but not the air.
5.Will it measure the temperature of the pool outside?
- Yes, it will. It also measures the temperature of water in an open container.

- Do not use solvent to clean plastic lens
- Do not submerge the unit in water

    This thermometer has a good fit in hand and works fine. I am using it for a month and works reliably. I was in hospital and saw that nurses check the patients fever on the forehead using similar thermometer. As having a new baby I though this could be a useful thing. Indeed, for quick checking of body (or any surface) temperature it is a handy tool.

    This is a nice tool, one issue I found : The `` set'' button ... the big red one that takes a snapshot of the current measurement, what this means in real terms is that you are much more likely to throw the laser dot off the target by the act of pressing the button, a softer-touch `` set'' button would help to mitigate this issue
