"The Chain Saw Buddy can be very useful for specific circumstances - you have a lot of medium-sized logs (7"-12") on the ground, and want to chunk them up quickly without dulling your chain. The Buddy will work with other sizes, but smaller logs tend to spin, and larger ones are more difficult to place in the swing arms. Don't plan on trimming branches or felling trees with the Buddy on, and it will be necessary to occasionally tighten it during use. That said, the product works fine, attaches and detaches in under a minute, and makes short work of downed logs without the necessity of a peavey or sawhorse, and keeps your chain sharp."
