[EX Q]: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.
[EX A]: Negative

[EX Q]: Add these ingredients:Flashy music, beautiful ladies, sexy dance moves, scanty clothes (no nudity), beautiful landscapes, and even some seaside hobbies... and what do you get?Wait a minute...Now add a film editor who thinks his amateurish effects are more important than the above ingredients. All the above scenes of the hobbies, the ladies, the landscapes were all spliced and edited into each other for a "strobe" effect of split second images so that you can't focus on any of it.Now what do you have?Probably a yard sale item in the 10 for a dollar bin. I may buy some of the earlier volumes to see if they're the same... wish me luck.
[EX A]: Negative

[EX Q]: I had high hopes for these to make my new Jawbone Era usable.Unfortunately, they are hard to fit, are not as flexible or form fitting as I had hoped and overall could stand to be much improved.Buy them if you have no other choice, but don't expect much or you'll be disappointed.
[EX A]:
Negative
