Review: An AC/DC power converter is a very basic item, so I had little doubt that this sub for the expensive Apple original would be effective, though not stylish. Unfortunately, we have had problems. The Powerbook started delivering electrical shocks and inconsistent charging with this adapter, and they got worse when we moved to a country on 240V. I know that the shock problem comes from the Macally adapter because I have another PB and an original Apple power supply, so can do all combinatorial tests. I like Macally and have several of their other products. I probably just got a bum unit but unfortunately cannot deliver a positive review based on previous experience with the company.

Review: ...I have ever read.Excellent read for the layperson. Most relevant to our current economic crisis in America. Every politician should be required to read this book. In fact, every classroom teacher should read it, as well. Explains the mess our government has created and why its continued destructive policies are leading our country to assured economic collapse. Policies based entirely on fallacies!!

Review: I enjoyed the 1st Transformers movie for what it was. Found the 2nd to be unwatchable. This one is better than the second one but what is that saying.
