[EX Q]: Although good quality product, it doesn't fit my ear at all. None of the sizes fit comfortably or snug. I can't use it at all and just wasted my money.
[EX A]: Negative

[EX Q]: I went into this movie hoping it could be better than TF2. It is, but not by much. I'm going to be honest. I think Transformers 2 is one of the worst movies I have ever seen. I don't know why I saw the 3rd one, but the Chicago part looked interesting. Little did I know it would take 2 long boring hours to get that part. On top of that. It wasn't even that impressive. I hate Shia's parents. I hate his new girlfriend. I hate Michael Bay humor. I hate this movie and I hate the fact I spent 12 bucks to go see it. I don't think Michael Bay understand that everything gets boring without a plot or some kind of tension going on. It's so BORING. I literally sat in the theater hoping it was over only to look at my watch and see that only 10 minutes had passed.
