Love the idea, but the quality of this product is very very cheap. The velcro strap unthreaded and ripped right out of the base compartment as soon as I pulled the item out of packaging. I still use it, of course, however the convenience of having the bag dispenser hang from my wrist or belt loop is no longer and option. The positive: it's very light weight.
Velcro wore out fairly quick, so I just hot glued the strap together. Bag is perfect otherwise!
