The sound is too small.
I think it's salty.

Received already charged. Put outside alarm worjs great 2 clicks for different settings in light.Highy recommended. Alarm loud enough.

Excellent, does the job I intended them for. I've bought 4 and am in process of ordering more. I have poultry and was tired of the dang crows eating my ducks eggs constantly as they often don't lay their eggs in a nesting area. I turn them on at night and turn off once I've collected their eggs each day. They have worked fairly good, I've only found 5-6 destroyed eggs since putting the first one up several months ago. Last year I lost over 12-14 dozen due to crows. Plus I've noticed my ducks have learned to trigger the alarms by moving into the sensor path when they hear the crows nearby. I'm going to use them around the outside and inside my garden too this year to deter squirrels, rabbits, crows and anything else deciding to try and get a free meal.
By the way, the sound doesn't seem to bother my chickens, ducks or guineas, just the wildlife. Their egg production has maintained normal average too.
