[EX Q]: At 60 pages,this is over-priced and not a course for adults. As basic instruction for those 10 and under, it is probably okay. For anyone who even doodles while talking on the phone- forget it!
[EX A]: Negative

[EX Q]: I got these for my jawbone headset. Many had said they work great. but for the life of me i cant figure out how you get them to work short of superglue and even then they are too quiet to hear so i guess they work on the jabra they are designed for but not the jawbone.
[EX A]: Negative

[EX Q]: Book is a great read. Intriguing from start to finish. Cant find anything wrong to say. Would reccomend for beginer to advanced readers.
[EX A]:
