question:
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: This game has some good qualities, but the pure racing person will have issues, as you gain $ for running into objects and cars, which blows. You are in a race and losing, so blast your car and everyone around you to get $$ for the next race. Realistic? Not. They don't even have a view from inside the car, it is a bumper view with no part of the car visible. The interface with arrow buttons is bad, and you can't even race online, just by LAN. In short, stick with Leadfoot or DTRSC and you will be at least $40 better off.jc

Review: glasses are awesome. They look great and they are larger than your average martini glasses. All my friends loved the glasses when I had a martini party.The shaker looks great, but alas, it leaks all over your hands when shaken, despite having a seal. So be careful!!But for this price, it's still a great buy.
