JVC Everio GZ-MG21 review:

 

main content Hard drive camcorders seem like a great idea. A tiny hard drive in a small camcorder case can record hours upon hours of video without having to switch out a tape or a DVD. Unfortunately, JVC's execution falls short; just like its nearly...

Light and tiny; many hours of recording time.

Poor video quality; awkward control scheme; image stabilization is a joke; not for big hands.

JVC GZ-MG21

 

Lightweight, easy to use, good reproduction, easy to edit and transfer to DVD, more than sufficient memory.

My first camcorder. Very impressed by lightweight and ease of use, makes you more inclined to use it or keep it handy in your pocket.

Standard battery doesn't last too long, a car charger would be handy.

Excellent product for the money for the average family user.

The battery life of the battery supplied is not the best for long term use.
