These are the only alarm clocks you should consider.

Our pick
“A serene alternative to loud alarms, this clock induced a gentler wake-up (a simulated sunrise accompanied by birdsong) than any other clock we tried. But it’s pricey, and it’s harder to navigate than the others we tested.”

Our pick
“Our most affordable pick, the RCA has an easy-to-read display and a very loud alarm that will wake even the deepest sleepers.”
