Example Input: Didn't last very long! Gave it to a friend after I upgraded phones and it only lasted her about a week until it rarely would charge the phone. Planning on returning it.
Example Output: 2

Example Input: I like the dark gray color and overall look of the sheepskin. This seems well made, but unfortunately gets too hot for me and within minutes. I ended up flipping it back and forth to get a 'cooler' side for the duration of the ride, eventually giving up and removing it. And it wasn't even warm/sunny. The search continues.
Example Output: 2

Example Input: I was looking for cable and luckily I found this from Amazon. I like how it comes with three in a pack and I can tell the material is durable and well made. Considering the price, that's a great buy!
