Language / Experience or opinions of The Travel Linguist? [4]

I've had an interest in learning Polish for some time. My Paternal Grandmother's side of the family is Polish, and I would love to visit Poland someday! Where I've lived, over the years, has not allowed me to find a tutor, or take a class. (I know this would be the optimal way for me to learn.) However, I came across this video, and was wondering if anybody had experience with this learning tool? Its on Amazon for around $20, and seems like it might be an alright start to learning pronunciation, and basic phrases. Thanks in advance for replies!
