Tried out my new Jaw Saw yesterday for the first time, and it was perfect for trimming and pruning. While it may be a bit heavy when using the available pole extension, it works great at an arm's length. Being able to easily and safely cut up branches on the ground for disposal is a real plus, too. And yes, this device feels and looks much safer than using a small, standard-type chain saw.
For those who have had issues with the chain coming off, I can see three possible preventive steps: do not use it for very small or bushy branches - hand clippers are better; don't "rush" the saw into branches - just take it easy and let the saw do its work; and, take a minute to clean out the jaw area and back toward pivot area of the chain's housing - this will avoid building up of debris.
For the price and its function, this is a great tool for homeowners who do not regularly need or use a standard chainsaw. I have and use a number of other WORX products, and this looks to be among the best. Another great WORX product for lighter,homeowner use!
