If you bought an e-cigarette that didnt work well or didnt work at all you might not have much recourse because the company could be gone before you tried to exercise your warranty rights
Fortunately, these smoke detectors each come with a sealed lithium-ion battery that lasts up to 10 years, and the unit will notify you when the battery life has ended, so you wont have to worry about replacing batteries
Though they admittedly can be difficult to get your hands-on in between drops as their immense demands always results in them going quick, the Prometheus Design Werx Ti-Lighters are definitely worth a look when shopping for a flame to add to your everyday carry

For example, our top pick, the First Alert SM500V, uses two AA batteries, but many states now require models with 10-year sealed batteries
When buying or installing new ones, first check with your local fire department for the legal requirements and building codes for smoke alarms where you live (First Alert published a state-by-state list here)
