Ex Input:
The bag was good to look at but unfortunately, it stank. I tried saddle soap, several different internet cures, leaving outside in the cold for several days. Nothing worked. It still smelled like rotting meat. It's out in the garage. I wanted to return it, but the seller is in another country so returning it is more expensive than just throwing it away.

Ex Output:
1

Ex Input:
Very chic, clean, and easy to use. However, after having got just a few months the band has begun to snag my clothing or the clothing if others. Wish this wasn't the case & now I'm stuck with it.

Ex Output:

Ex Input:
This waffle iron is messy. It leaks out easily, which I expected but super hard to clean off once it does. It leaks through the crack in the back of iron where you can't clean. There is a slide botton to let you choose the darkness or lightness of your waffle but it's loose and flimsy. No matter which setting I use the waffles come out super soft. I've changed recipes thinking that was why but I get the same results.

Ex Output:
