This trimmer - does not extend - it is basically a trimmer on a non-extendable pole. This makes it pretty usless in tight spots. It's balance is off, and the trimmer can not be used without the attached pole - it would have been simple to make it convert to a small trimmer (less the long pole). I like the convience of a cordless trimmer, and the trimmer does its job. I just think this product could be so much better. Pass on this until they do some redesign.
