Will this save you time?  Definitely.  If you have a hedge to remove it can save a lot of time and work.  The last section of hedge I removed I did with a pruning tool and it took weeks to get every single spindly branch growing out of the ground.  This tool never bogged down and it really did breeze through 4" branches and all of the suckers coming up all around the trunks.

Will this save frustration?  Maybe.  No matter what I did I constantly had to clean branches out of the jaws and tighten and oil the chain.  If I got brave and didn't tighten the chain after a few minutes the chain would come off and I would have to sit down and put the chain back on (which is a pain because you have to try to keep the jaws open while you do it).  Oiling?  Forget it if you are going to use the included oil bottle.  You cant squeeze it because it is made out of such incredibly hard plastic and the screw top spout on top doesn't stay open.  Pure garbage.

If you plan to trim a few branches here and there I *highly* recommend this tool!  If you have 50 yards of hedge... I recommend it also.  It will save some time, but be prepared for a little frustration if  you have the same luck I did with the chain.
