question:
I was very excited to buy this scanner and was pleased with its size and weight. However, if you have a Vista operating system, like I do, IT WILL NOT WORK! The company told me that they stopped selling this product over a year ago and there are no driver updates available for this product. If you have an older computer and an older operating system this product might work for you. But as for me it was a waste of money!
answer:
Negative


question:
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.
answer:
Negative


question:
This is my first encounter with Yoruba and I have to say that CDs are really helping. However, the book is very short and not particular about certain aspects and details of grammar and other nuances - for someone who NEVER spoke Yoruba and doesn't have anybody to ask for a clue, it leaves a lot of questions unanswered - for this, however, there are hopefully other Yoruba textbooks.On the brighter note, I would like to add that the book does a very good job in giving a little insight on Yoruba people and Yoruba culture in general. I would recommend it as a good start book for anyone who wants to learn Yoruba - you can't go wrong with it.
answer:

Positive
