Window smasher is the point on the bottom just for reference, i like the idea of this, and i like being prepared for any situation. So next time i do plunge into a river i will be able to come out alive.. Thanks to this product.
This aside the use is very handy, makes my Car Charger have 2 ports and a further 2 USB ports which is handy as most portable electronic devices have USB chargers or the ability to purchase one to work with your product. so overall 5/5 recommend.. cheap too
