Query: Best Item Ever!

My experience with this item was totally opposite Talana's. (Perhaps this model has been refined over time.) We always dispose of our dog's 'droppings' and had to remember to bring a bag or two along. This is so handy - a bag is always right at hand. We have always refilled with the official Bags on Board refill packs; the top of the bone rotates off and the replacement bag fits over a stem in the center (sort of like replacing a toilet paper roll). My husband initially had a little trouble unrolling the bag too far when he tore one off, but they have recently added a white bar to the bags so you can easily see where to tear the bag off of the roll now. This item is wonderful!!
