[EX Q]: This product worked for 4-5 times and the rotation stopped working. Batteries run out or lose power after 3-4 uses. I would read reviews before buying another one... I am looking into the Hitachi wand massager now and I believe I will buy it since is a power operated toy and will never run out of power.Not impressed with this product.
[EX A]: Negative

[EX Q]: This is one of those beautiful moments. You know Dolly has been kicking around major labels like a tennis ball. You know that women singers past 40 rarely get airplay. You know Dolly is a wonderful singer whose creative potential has not lessened. You bring home her latest CD on the smaller North Carolina-based Sugar Hill label; and you wonder if her recording career will be reduced to small independent releases. Then you put on the disc. Wow! I like Dolly's philosophy: When all else fails, make one of the best albums of your career. This album is nearly flawless. The steller bluegrass players lend an integrity and enthusiasm which keeps taking Dolly even higher. The songs of spiritual faith are transcendent and not preachy. This is a magnificent accomplishment. If you've like Dolly or bluegrass music, don't miss this marriage of the two. Unforgettable!
[EX A]: Positive

[EX Q]: its entirely beyond me how with every film lloyd kaufmann directs, it outdoes the last. sheer genius.this is one of THE greatest flicks ive ever seen in my entire life. with hours upon hours of dvd extras, this two-disc set is the greatest dvd since terror firmer. i cant even begin to describe how amazing this movie is. indeed it is the true sequel (although toxic avenger II is a guilty pleasure of mine).i think the most amazing thing about this movie is it was made with 1 half of 1 percent of the amount of money a common hollywood film costs. utter and sheer genius.
