Example Input: Would a great timer if it was waterproof. It would seem like something that is being used outdoors in most cases would be waterproof especially something controlling sprinklers. I had one growing season but failed a few weeks into the following season after the control shorted out after getting wet. It performed so well that I thought I would just try another and cover the control as best I could with a plastic bag. It failed after only a few months and for the same reason even after protection.
Example Output: 1

Example Input: ended up returning these, the material feels much better than the faux leather ones but these just are not very comfortable at all to me. I'd stick with the 6mm one and put one of their covers over that much more comfortable
Example Output: 2

Example Input: If you like Tony Hillerman and are invested in his characters, you will enjoy this book. However, this series has gotten a bit long to me. The plot is weaker than in earlier novels. There is less Indian lore. Also, there is a rush at the end to the up loose ends that seemed almost artificial.
Example Output:
