Example Input: I have had many Bluetooth's and this one is the best so far. The sound barrier has been the most important part. When I have both ear buds in I cant hear any outside voices or anybody close to me in distance. It's important to me. My boyfriend is in Texas and when we video chat I need to hear him and only him and these allow me to do just that. Thank you wireless earbuds.
Example Output: 5

Example Input: This is a beautiful top and is exactly as pictured. I liked it so much I ended up ordering it in two more colors after I received the first one. The only important thing to know is that it is extremely delicate and for that reason I'm worried that it won't last through many wears. The front part are two very thin and delicate pieces of lace that are seen together and I can absolutely imagine it tearing, Snagging or unraveling. That being said I have washed this shirt in the regular wash and left it to hang dry and that worked really well with no issues.
Example Output: 4

Example Input: I used it once and bled. Next time I'm using the electric nose and hair trimmer. Before the electric I bought the nose and hair scissor because another scissor I have, labeled Titanium, is so sharp and so good, that I hoped the nose and hair scissor would also be good (but for me now, forget the Titanium scissor, probably too sharp, and also ;the already bled with the nose and hair scissor. Besides, the nose and hair scissor probably can't do the job).
