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'm a fan of silent films, especially the long German epics. I'm not a big fan of silent comedies, but I do enjoy them occasionally, especially Chaplin. Although I've seen my share of poor quality films, this set is virtually unwatchable. Besides the poor quality of the print, title cards are missing, long scenes are cut out, half the heads are not visible in many scenes and they have the most annoying musical score I've ever heard. I won't waste any more of my time typing or your time reading. Although $18 for 32 shorts may sound like a good deal, it isn't. Take the $18 and put it toward Chaplin's 3 Essanay Vol's or his 90th anniversary Mutual set. You won't believe the difference. After purchasing those sets, I threw this one away. Now I'm just waiting for someone to restore Chaplin's Keystone shorts with Mabel Normand.

True

Review: There are a few things I didn't like about the tape. Firstly, the price is too high. Secondly tape is inconvenient for a spoiled by technology user. It's much easier to work with DVDs and their menus. And lastly, I realized that I'd rather spend 70 dollars on 4 monthly group lessons and learn basic steps and routines of one dance then try to master all by myself while watching a tape.
