COMMON SENSE

The laser IS bright! Even in normal temperatures and daylight it is recommended to limit it to 30 seconds or less per use to avoid heat buildup.
Just like the laser pointers you use to play with your pets, you should ALWAYS avoid direct eye exposure to laser beam. You wouldn't stare into a very bright flashlight, and you should not allow direct contact to anyone's eye (this includes your pets! Love those little guys!) Exposure to the eye can cause permanent damage, so don't do it!
Please keep this out of the reach of children. You have the responsibility to supervise the use of this laser. When not in use, it is always a good idea to remove the battery. This is a good way to help ensure persons of an appropriate age do not have access to it.
In some countries, laser pointers such as this may be illegal to own and/or use (especially the higher powered ones). Therefore, by purchasing these products YOU (the customer) accept all responsibly and liability to determine and fulfill the requirements and limitations of use or resale of these products in accordance with your country`s laws and regulations. In the event of resale, you also agree to include this notation in the product description, so that any potential buyer can also make an informed purchasing decision.
