A:Â Thank you for reaching out. ANSI/UL standards say a fire extinguisher must stay pressurized for at least two years. Tundraâ„¢ Fire Extinguishing Spray has a three-year Performance shelf life, which is printed on the can. We chose a very conservative time frame because this is a life safety device, and the unit does not have an indicating gauge to tell the user if it is pressurized. The unit may last for five years or more.
A:Â Consumers Reports rates this a "Do Not Buy". Buy a conventional one.
A:Â If you look at the label of the can (on the Target web page) it says :3 year limited warranty".
A:Â Thank you for reaching out. We do not recommend leaving this unit inside a vehicle.
A:Â The lablel on the can, visible in ad above, says : do not expose to heat
