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 bought this on a whim, as it was the first Zen garden that I could find. I did not look at the reviews, and immediately regret it upon receiving my Zen garden. The other reviews summed it up nicely. The product is exactly what you pay for.Image:[...] - You can see the gap between the border/frame and the bottom piece. The tacks were put in, but did not hold the board to the border/frame. You should probably buy some wood glue, push lightly to separate the border, then press it back together with a small vice.
