Some of the chainsaw videos are good & some aren't.
Seems like most of 'em, especially if the guys are young, have this ridiculous LOUD heavy metal music playing.
Here's a few of the Echo.

I thought this video of the EGO was good. It explains the importance of using a higher Ah battery. Usually, as the Ah of the battery goes up, so does the price of the saw.
