Question: 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.

Answer: Negative


Question: I don't quite understand why Courtney is allowed to put these things out, and even more surprised that the other members agreed to it (since they have to). Everyone who already put out the 50 bucks for the box gets a whole three song bonus, songs which don't even sound like anything special. Nirvana was an awesome band who made some of the greatest music of all time, and this CD does reflect that. It's a good CD, but it's useless. It's nothing we don't already have. If they're going to put more Nirvana stuff out, it should at least be stuff we haven't heard. Just buy the three songs off of iTunes or something and save yourself the money from buying this CD.

Answer:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
