Example Input: All I have read about these was pretty much true. You can remove the rubber piece and press these over the part that it was attached to and they will stay, but they do come out with a little tug. A fine line of rubber cement will fix that though, and it peels off if necessary. But the great thing is that they will hold the Jabra in your ear without the ear loop. And that's huge, especially for someone like me with really weird shaped ears that nothing else [except an over the head headset] seemed to work. All in all worth the cost easily. I just wish you could order multiple pieces in one size only. If I lose the 1 that fist my ear I have to buy a 6 pack again just to get the one that I need.
Example Output: Positive

Example Input: It does an excellent job on mildewed wood such as decks and deck furniture without using chemical mode which is the only weak link in an otherwise strong chain. Unfortunately, the only effective chemical solution is chlorine which acts more or less on its own but cannot be used with this machine. Safe cleaners, such as Simple Green are no more effective than when used without them. Other than that, it's a great product.
Example Output: Positive

Example Input: This movie kicks a** all the way and I can't wait for this to come out on DVD because it's an excellent movie!
