Alarm exactly as expected - colour, size etc. Tested it when it arrived and it emits a deafening alarm - enough to scare anyone off. Also has a very handy torch incorporated into it. Bought for my daughter at Uni in London - sincerely hope she never has cause to activate it but it has made me feel better knowing she has it with her.
Because of the location of the key ring, and the location of the corded pin (used to activate the alarm) which is at 90 degrees to the chain; it can only be operated with two hands. In other words, you would need to hold the alarm in one hand and pull the pin with the other. One could have expected that you can operate it with one hand, a lady (with her customary bag) may not have the time to use both hands in a time of crisis. Pulling at the corded pin whilst it is clipped to anything via the key chain does not result in the pin being removed no matter how hard we pull.
