Example Input: Claimed to fit Coralife RO system It does not. Too tall. Didn't need to change them until last week. That's when my aquarium maintenance guy showed me that it was impossible. Disappointing, now the return window is closed.
Example Output: 3

Example Input: I LOVE THESE! I got them in this gray color first & then bought 2 more colors because I just loved how they fit. I am 5'4" & 145lbs & I got a large size & they fit great. They're super flattering & can be dressed up or down depending on what you choose to wear with them. One of my fave purchases on Amazon!
Example Output: 5

Example Input: This particular Pop! is of lower quality, which explains why it was an "add-on". You can see the glue at the back of Benny's head, and the paint job on his face is less than stellar. Just goes to show, you get what you pay for. I will not be buying something as an "add-on" again.
Example Output:
