[Q]: Not so much a read as a chore. The characters don't come alive...they were not interesting or engaging. It is hard to finish the book because it lacks any substance.
[A]: Bad review

[Q]: This is an excellent product. It replaces a unit that broke after some time. The old one had the battery door open and needed to be recharged. You need two AAA batteries. It's lightweight - good to travel with. Batteries can last 2-3 weeks between charging. All in all I'm very satisfied with performance - no complaints.
[A]: Good Review

[Q]: I received this item, which was well packaged to prevent any damage. My original adapter gave out and the tip of it broke off. So after searching for a good replacement in Amazon.com, came across this. It looked very like my old one even though the brand tag was missing. It does not work with Nikon D7000 Camera....The camera is new model, it just says battery error!Waste of money...
