I have to give high Praise to looptworks.com for their customer support.
My backpack from TechEd Europe had a bad zipper and would not close anymore soon after getting it rendering it pretty but useless
On a shot in the dark, I emailed Looptworks on their contact form and was only asked for pictures of the damage.
A New comparable bag is being FedEx’d to my location in Ottawa right now. GREAT CUSTOMER SUPPORT and NO HASSLE!
Here is the replacement unit I am receiving – http://looptworks.com/shop/bags/kasum-backpack/
