[EX Q]: This item was much shorter than I expected it to be. I have an alaskan malamute and this did not do the trick in trying to help with his pulling. If you have a small dog, this will work for you.
[EX A]: negative

[EX Q]: It’s exactly what I needed, easy to cut and put in my shoes. Such as running shoes, but it needs more space after put the deep heel insert. Overall, it's good.
[EX A]: positive

[EX Q]: I wanted to love this bag, the design is great. But you get what you pay for I guess. I bought this for a trip out of town and the first zipper I touched popped off the top pocket when I started packing. I managed to work it back on there and then reminded myself to be gentle with it. When I got where I was going, the same zipper came off again. I didn't really have time to replace it so I just let it be since the entire thing can be zipped up. Or so I thought. When I was packing my things to come back home the outside zipper that closes the entire thing came off the track. It's a pretty cheap bag and that is reflected in the quality.
[EX A]:
negative
