[EX Q]: eargels replaced old and lost ones that came with my blue tooth. they fit well and got ere quicker than expected.
[EX A]: Positive

[EX Q]: This product requires a stereo player in which the balance is turned totally to the left. Most auto systems have that capability. However if you have Dolby or SurroundSound, it can be difficult (and maybe impossible) to play the cassette without hearing two recordings at the same time. Unfortunately neither the packaging nor the website will warn you of the problem. You therefore should think before buying. Once you have opened the packaging you may be unable to return the product.
[EX A]: Negative

[EX Q]: I guess I should have read the last review or even the fact that the description says Landscape. I didn't think it was necessary, it's just a book right?I guess it's supposed to be easier to read in bed. I just thought it would be cool to have the Scarlet Letter be a red book.If you buy this book you will be holding the book like a wall calendar and reading in two columns; first the two columns on the top page and then two columns on the bottom. This just seems really irritating to me.
[EX A]:
Negative
