DEFENDER ULTRALOUD PANIC ALARM

This very, very loud (143dB!) panic alarm could be useful in these days of urban attacks and bike thefts. As well as being shockingly loud, it has a dazzling, high-intensity strobe light that’ll change the balance of power in a threatening situation, and’s designed to shock and disorientate an assailant, triggering them to take flight. It’s activated via rip-cord lanyard, allowing you to hang it from your bike or attach it to your belt or keys or, off-bike, your bag or rucksack or at your waist or in your pocket.

The Defender Ultra-Loud Panic Alarm is priced at just £10.95 and is available from www.defendersecurityproducts.co.uk
