Product review (4 stars): Handy thermometer
This product works as advertised and the seller sent an email to make sure my order was good.  So far no alarms have occurred so im not sure how far the sound will carry if it goes of in the middle of the night and I'm asleep, for example...but still better than nothing.  I wish the screen was lighted....I have to detatch it to read it in low light.  Luckily its attached with Velcro so not a dealbreaker. **update**  the alarm is not super loud unless in same building.  My freezers are just outside my back door and the alarms were somewhat audible.  Biggest issue is the alarm sounds at a certain temperature not when power goes off and temp starts dropping.  I really need a power alarm not a temperature alarm.  Not the fault of manufacturer. But something to keep in mind.
