Question: Is this product review positive? Title: Poor design disappoints Review: My 9-year-old son got this for Christmas. The simple stuff is easy to make using small gears lying flat. We tinkered together for a while to make some of the complex systems displayed on the box, but frankly, they are impossible to make. I believe another reviewer for a version of this toy said that it would require adults using superglue to hold pieces together to make the cool stuff. I agree. The pieces do not fit together in a predictable or stable way to allow gears to turn as you build a tower (well all but the simplest tower with the small gears). I'd build a tower only to have it not work, or have it fall apart because the gears would only mesh if the pieces were not firmly fit together. The brief instructions don't help. The instructions crucially lack drawings of sample set ups. My son gave up after 15 minutes and I did a half hour later. Answer:
Answer: No

Question: Is this product review positive? Title: Excellent overview about mobile standards and markets Review: The book is very structured and gives an excellent overview about all major mobile standards, technologies and markets (Europe,US and Japan). I give it 4 stars because it was written 1997 so that the market data are not up to date. A 1999 edition would clearly have 5 stars. Anyway it's a buy. Answer:
Answer: Yes

Question: Is this product review positive? Title: deserves a zero Review: cheap, brittle plastic. About as sturdy as a styrofoam sandwich box made flat. Cracked already when it arrived, cracked more when I picked it up, cracked some more when I put it down. Not worth any amount of money. Answer:
