[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.
[A]: Negative


[Q]: This CD is great for some people, but I think a lot of other people are buying it who maybe shouldn't.For the Nirvana fanatic with money, get the full boxed set, you will probably find the DVD and the book to be worth the extra money, even if you don't listen to the added tracks.If you aren't a fanatic, stick with the albums. You will not like the low sound quality of the recordings.Now, for the Nirvana fanatic who's a bit short on cash, but absolutely has to have "Do Re Mi" as part of his collection, that's who this is for. "Do Re Mi" is an excellent track, one of Nirvana's best...so if you are a serious Nirvana fan, you DO need to have that one.
[A]: Positive


[Q]: I picked these up locally to use at the table. Only used few times when a handle on the salt mill broke right off. They worked OK before breaking, but didn't have much output. They also appeared to be difficult to refill, the opening is only about 3/8 of an inch square.
