Sonic Alert Sonic Bomb Junior review

The Sonic Bomb Junior is the smaller sibling of the Sonic Bomb. Sonic Alert pitches it at heavy sleepers who have limited space on the bedside table, and the product page lists the same three cues as the bigger clock: a bed shaker, super bright strobe lights and an extra-loud alarm. That combination is what matters for someone who is deaf, because the shaker and the light each work without hearing. Sonic Alert gives fewer specifications for the Junior than for the full Sonic Bomb, and it does not state a decibel rating on the product page, so heavy sleepers who also rely on sound should look at the 113 dB models. The appeal is price: it cost $34.99 when checked, down from $53.99, which made it the cheapest verified clock here. Shipping is free and returns run 30 days.
