Example Input: I bought this knife December 2018 and has been great thus far. The only downside is that the clip used to attached the knife to a pocket or belt is held by 3 small screws. With time and the weight of the knife one of the screws stripped and no longer held the clip in place. I remedied this issue with a drop of gorilla glue. Now it doesnt move and holds the clip and the knife in place.
Example Output: 5

Example Input: Amazon sent me a wrong shelve that fits only 4 pairs instead of the ordered 5 pairs. Then Amazon did it again with the second order. The shelves are terrible, flimsy, the front horizontal supporter is made from the papers and gives way right away. Terrible product, terrible service. Nobody at Amazon pays attention what they they ship.
Example Output: 1

Example Input: Lamp is used as a bedside lamp. It is solidly made and just as pictured. This is not something that will tip over. Was pleasantly surprised at how well made the lamp is. Might not work if you have a small or lightweight table due to diameter of lamp and weight of lamp, but it is perfect for my needs. Color of lamp is a soft cyan and is as pictured on the website.
Example Output:
