Every laser pointer and portable laser from Dragonlasers should last you for at least 5000 hours if you look after it properly.In practical terms, that means if you use your laser for 3 hours a day every day, your laser will last you for over 4.5 years.

Here are some tips on looking after your laser to make sure it does last for over 5000 hours

When not in use, do not keep the batteries in your laser. If the batteries are left in your laser pointer or portable laser, they may cause corrosion of the battery terminals and other problems.

Always keep the lens covered when your laser is not in use. For portable lasers such as the Hulk, this means keeping the lens shutter closed. For laser pointers such as the Viper, you can cover the lens with tape or a similar weak adhesive.Just be careful the tape will come of the lens cover cleanly. lens cleaning tutorial video

Your laser should be stored in a dry place with humidity of no more than 45% and temperature should ideally be no lower than 0 Celsius and no higher than 50 Celsius.

Handle your lasers gently. These lasers are sophisticated electronic devices with delicate optics that should always be treated gently, never roughly.

The lens are very easy to be damaged or scratched when cleaning them so great care should always be used. Ideally you should get a professional such a camera repair/service person to clean your lens for you.
