Example Input: Really sturdy well constructed suitcase. What I liked least about the suitcase is that it was not the one shown in the photo, the black with the orange trim and wanted it to match the same orange and black suitcase but in the larger 25" version I had purchased at the same time.
Example Output: 4

Example Input: Bumper came with scratches and a dent that cracked the chrome. The top pad also wasn't attached correctly. This has caused me to miss an important deadline. Only upside is it came a day early.
Example Output: 2

Example Input: Arrived broken. Manufacturer defect. Two of the legs of the base were not completely formed, so there was no way to insert the casters. I unpackaged the entire chair and hardware before noticing this. So, I'll spend twice the amount of time boxing up the whole useless thing and send it back with a 1-star review of part of a chair I never got to sit in. I will go so far as to include a picture of what their injection molding and quality assurance process missed though. I will be hesitant to buy again. It makes me wonder if there aren't missing structures and supports that don't impede the assembly process.
Example Output:
