Quake Alarm - Sold by: Innprodica - Includes Improved mounting Hardware, Improved Shipping Packaging to Prevent Damage and a New Quick Install Instructions Sheet. Fully Adjustable. Be Prepared!

I installed this device in our bedroom. Primary intent is to alert us when we're asleep. Hoping for no earthquake that would trigger this (who wants a calamity, right?). Literally, this thing is loud as of recent testing. Minus one star for the adhesive which is not strong enough. I got a call from my wife when I was at work, I was told this earthquake alarm triggered and they heard it from the living room downstairs so they all headed out. Anticipating an earthquake would soon happen, nothing. The alarm is still triggered so my wife went upstairs to check, lo and behold, it is on the floor.I investigated why it has fallen off as soon as I got home, as I've mentioned the adhesive is not strong enough. I've done proper procedures before installing this. Cleaned the wall where it would be installed, made sure it is totally dry, leveled the device before finally attaching it. To remedy the issue, I bought an industrial strength 3M plastic velcro and replaced the ones currently on it. So far, it hasn't fallen off.

Mounting this unit is comical, sticks on the wall with velcro and comes with tiny nails to help hold. Mounting it is a problem, I just put it on a shelf, gave up on wall mounting, it fell off.It makes loud noise while working and handling it, they recommend taping it while working with it.The sensor is a pendulum and V, very basic. Requires adjusting the sensitivity, the proximity of the pendulum and V sensor. Not clear if it senses P wave or S wave or both, manuals and pamplet do not say.Would I recommend it? Yes. Get this one or any other seismic alarm, preferably P wave sensing for the heads up alarm.

It did detect an earthquake of level 3 perfectly with the highest precision adjustment!Would've been great if we could change levels of detection by steps tho, or at least some indication or bar would've been great, but still an amazing device, that works.

Gave us about 5 seconds before the first shock hit, but because we new what the alarm was we we moving not laying in bed wondering what it was.

I bought it last november. I was courius about how it works under a real quake. Yesterday and today in Bogotá we experiencied 3 earthquakes ( 6.2, 5.7, and 4.8 ) from a relatively close area near Bogotá. It worked as I expected. It gave us the alert seconds before some private alarms started to make noise when the earthquake happened. Not sure how much time it anticipated the S wave coz of the panic. Still im happy to have some precious seconds to react.

Does what it is supposed to do.But it doesn't reflect it's price. Doesn't even comes with the battery. $50 plus for a buzzer, a pendulum and a cheap plastic case sounds expensive.

Useful device and it works as expected.

Every California resident should have oneI would highly suggest nailing it onto the wall the first night this product fell off the wall at 2 AM scared everybody in my house
