[Q]: Adapter worked flawlessly for six months, then became intermittent. Seems to be broken or shorted somewhere near the connector to the computer. Even the ridiculously flimsy cord from Apple lasted longer than six months, so I can't say I'm pleased. Macally says they'll sell the connector cable separately for $17.00 which is not much of a bargain.
[A]: Negative


[Q]: The lady is kinda annoying. But the videos made me feel prepared and made me feel comfortable with my decision to not go to any formal classes, these were more than enough.
[A]: Positive


[Q]: Great to deal with. Very quick delivery. Very highly recommended. Thank you.
