Ex Input:
I ordered these in 2 colors....blue and purple, both of which arrived defective. The right ear piece only functioned sporadically without any input from my phone at all. Amazon is sending me a replacement pair but the same problem with second pair. Very disappointed in this product for quality control, however they were pretty great when working right. Will give it one more shot before resubmitting review. Don't buy unless you want to waste time trying out multiple pairs.

Ex Output:
Bad review


Ex Input:
I was rather disappointed with this book that promised to offer a true account of the real life adventure of one courageous pilot in the Spanish Civil War. While written very well and quite interesting, it does seem at times like an essay which reads more like history than fiction. The author apparently decided after finishing the manuscript (which includes photographs from his personal collection) about half way through writing it, that he would create a story around it.

Ex Output:
Good Review


Ex Input:
I had previously tried the regular version of this product and it was horrible for me. Now with this one I'm much happier! It gives me plenty more energy to last ALL day. The smell is ok but once you get used to eating them it's fine. Not a huge problem as they tend to go down pretty easily. I'd recommend them any time when you're looking for something that will give your body just what its needs in terms of protein (esp. compared w/ other products I've tried).

Ex Output:

Good Review
