Example Input: Excellent product. I was having difficulty hearing and also getting a comfottable fit with the included ear hook that came with my Jabra JX-10 Series II Bluetooth headset. I removed the hook and attached one of the 6 gels that came in the pack to the headset and found that the volume increased 40% and I was able to achieve a comfortable fit. The headset is small enough and light enough that the gel holds the headset in the ear. I was about to give up on this headset (and all earhook type Bluetooth headsets) prior to getting the gels. If you are looking for a comfortable (and econimical) alternative for earhook type headsets, I strongly recommend that you give these a try. They are well worth the price.
Example Output: Positive

Example Input: I didn't think much of this album when I first got it and listened to it, but after a couple of listens, I really liked it. In fact, it's probably one of my favourite Hollies albums. I usually listen to my music on my ipod or my itunes on shuffle, and whenever I hear a Hollies song that I don't really know but I really like what I hear, it's usually from this album. So I would definitely recommend it even if you are not a hard-core Hollies fan!!
Example Output: Positive

Example Input: My husband loves this book. He said he has learned so much and that this was the best book to learn how to build a timber frame house by.
