As you may know, I am a SIGG Mummy which involves us reviewing products for SIGG Eco Bottles. We've had bottles sent to us for all the family for both hot and cold drinks, and also food storage tins. Every single product we have, we use throughout the week and test them to destruction. Only you would really need to do some damage to destroy these bottles.
Take my bottle for instance: it comes out in my handbag with my every time I leave the house and comes into school with me on my working days. It's covetted by all the girls in the school, goes in many different classes and everyone knows which bottle I'm talking about if I've left it in a classroom. I've dropped it on the playground countless times. Granted, there are small dents in it to show for it's playground antics, but they just add to the appeal of my SIGG bottle. These specially crafted bottles are tough and durable, they can stand a fall over on the tarmac.
