Example Input: It doesn't fit exactly how the picture shows. I guess it might look different on some faces, but when I wear mine the skull from the top jaw looks decent, but the teeth are stretched out across my face. That's all you see is the teeth stretched out. It just a bit off like your wearing white paint.
Example Output: 2

Example Input: The club is excellent. Amazon's order handling was terrible. Can't be trusted to deliver expensive items consistently. Customer service on follow up was mostly helpless
Example Output: 1

Example Input: First off this sounds great and works fine for the most part but i HATE it. Technical function: call quality is very good. Strength is okay. some drops when phone in pocket. Design: ALL of the parts/surfaces of the headset (where you hold to put in your ear) are touch sensitive buttons. Each time this tiny thing wiggles while i'm moving and i try to re-seat it, i hang up or activate some function. Maybe you are supposed to grab it by the tiny microphone? i don't know but that's annoying. i use a headset when i need to move with my hands and this constantly falls out using varying sizes of ear bud. Battery charger stone: does not hold charge for 2 days. always dead when i go to use it. might be a motion sensing problem as i keep it in my bag. fully charged on the plane, dead the next day with no intentional use. no visible connections on my phone. decent product but be aware of these issues if they matter to you. i'm hoping i can fashion an ear hook or i will probably leave this permanently plugged in somewhere and seldom use it. waited too long to return.
Example Output:
