Example Input: I had high expectations for this little bag, but it didn't quite measure up. First the things I didn't like: 1. The zippers are either too long or need to be placed better. Whenever I opened the bag, my stuff would either fall out or I needed to hold it back from falling out. 2. The pocket for a cell phone is in an inconvenient location on the strap. Too awkward to use there. 3. The water bottle pocket needs to be bigger. I had a 20 oz bottle which barely fit. I had to work some to get it in. The things I did like: 1. Nice size not too little not too big. Holds what you need for an outing. I had a fold up umbrella, sunglasses and case and a few other smaller items in it for the day. Could even fold up a jacket to fit. 2. Nice to have hands free and able to access without taking it off like a backpack. 3. It is comfortable. Wore it all day at a golf tournament and it wasn't heavy and bothersome. I am going to keep it, but would really like it better with the above improvements.
Example Output: 3

Example Input: Pro: Picture quality is very nice Pro: Sound is good enough for the purpose Pro: Price is good Con: When the unit is rotated 180 degrees and folded shut (as it would be in a car mount), the convex monitor backing can push the function buttons behind it when even the slightest amount of pressure is applied (like a toddler playing with the TV with their feet). Often, playback is stopped as a result of these interactions. Con: The remote works, but reception at the unit is a little sketchy from just a couple feet away. Often have to push buttons more than once to get the unit to respond. Con: The headrest mounting case has a strap that covers the On/Off switch in the unit. Since you cannot toggle the unit's power from the remote, it can make things awkward. Con: The cigarette lighter adapter has a short cord (two feet long, tops). I was lucky and already had an extended adapter that fit this unit; otherwise, I would have needed to buy a different adapter to use this unit in the vehicle. It would have been too far away from any power source. I don't dislike the unit - and doubt it will get returned - but had I known these things going in, I would have purchased a different unit.

Example Input: After only using this lock a couple of times, the key will only turn part way, so the lock can't be unlocked. It took me about 10 minutes before it turned the first time, and now it's doing it again. If I can't trust a lock to open, I can't use it. This is worse than useless, since your lock could very well strand you.
