This book in the beginning was so slow that I finished a book twice it's length before I finished the first chapter of Tess of the D'Urdubervilles.

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.

Ex Output:
Positive

I'll admit it, I didn't have a clue what was going on in this book (which claims to be real, but is obviously a work of fiction), nor did I really have much of a reason to.UFOs...Men in black...Mothmen...Abductees...government coverups...sightings...It's all here, and regardless makes no sense whatsoever.I actually walked into this thinking it was going to be great, that there would be a wonderful story based upon the legend of the mothman, but no I was bombarded with 266 pages of "research" having no really meaning, or thesis. Honestly, I say avoid this like the plague.

Negative
