Question: Do you have to hold down the panic button or is it a 1-push on/1-push off function?
Document: I purchased this personal alarm, and I'm happy to say that it has exceeded my expectations. The alarm itself is about four inches long and 1/2 inch wide. This are just extimates; I havent actually meassured it. My point is, the device is really small and comfortable to hold. The lanyard is very convenient and easy to pull in case of an emergency. The alarm is very, VERY loud; I actually dropped it by accident while testing it. I highly recommend this product.
-For starters (minus 1 star) this is not exactly the thing that a minimalist would carry on their key chain.
Probably like a lot of these alarms, the pin pulls out of the body to activate. Very loud and easy to hold in hand. My girlfriend looped the lanyard around her purse handle for quick access and to prevent it from being swallowed by said purse and never be seen again.
This is something you find in those junk stores at the flea market. 10 for a $1. Made in China and packaged in those cheap little boxes. I never leave comments usually, but this ticked me off so much, just had to do it. Stay away.
The light stopped working after 1 short use. I suppose the bulb burned out because I inserted new batteries to check it out. I will say the alarm is loud. No one came outside to investigate, though. I couldn't return it because I lost it.
There are so many aspects that I like about this product! First, it fits very comfortably in the palm of your hand. I loop my wrist through the cord and then hold the device in my hand. Most people don't even notice you are holding it. Since this device is meant to startle any potential attackers, they wouldn't even notice it in your hand. With the wrist cord being looped around your wrist, you would have no trouble pulling the pin out to activate the alarm.
The dimensions listed for this product on Amazon are incorrect. The listing shows 2.5" x 0.5" (which is about the size of a small USB stick drive). Well that's nowhere close. The unit is actually 4" long, 1.5" wide and a little over .5" thick. That's a little too big in my opinion. Then again, in order for it to put out any kind of decent volume, it can't be too small. I get that.
the is awesome!! you can use it & keep you hands free, too ---i like to put the loop though my jacket pull & snug the unit tight---you can keep one hand on it & yank if necessary, to activate...then, can just throw it on the ground, in  the one motion!! yes! !it is extremely loud & will definitely attract a lot of attention.
seems to be a good product, ill ask my wife if she still uses it on the way to the door at work
product is ok, but couldnt really scare anybody unless you threw it at them. alarm is wimpy. hard to find and point.
