Question: I bought these to help with what I've read, to get the Jawbone to fit better. These ear pieces were hard to get into the ear no matter what size I tried. For a wireless earpiece you want to be able to get it on and off your ear quick if you need to, and these prevent you from doing so.

Answer: Negative

Question: I am using this textbook in a class and it is a whopper. Wonderful pictures, easy to read, clear colors and understandable. I've been working in prisons for 5 years and this book makes a lot of sense. You ought to read their sections on women in prison and on probation. I loved the parts on geriatric prisoners (old cons) and the death penalty. And it is easy to read. More!
