Rated 5 out of 5 by Been down under and back with my Stihl We have a steep slope (AKA cliff) behind our house that gets heavy brush overgrowth that has to be taken back regularly. I repel down and go for it. There is no other tool to use. My Stihl HSA 66 makes quick work of the entire job, including those pesky alder saplings, up to 3/4", no problem. My wife calls it "down under and back".Oh and there's our 20 foot tall Leylandii Cypress hedge. No problem. Straight as an arrow, flat as a board. The hedge, I mean. September 19, 2016
Rated 5 out of 5 by best in the field light weight yet powerful...works great...holds a charge for extended time... August 12, 2016
Rated 5 out of 5 by Good power, battery fully charged in less than 10 minutes Good power, cut through a tough hedge with 3/4 in branches in some spots and did not bog down.The blade is extremely sharp, probably sharper than all the knives in my drawer. It was so sharp it scared my wife and she said she wasn't going to use it.After she saw me cut through the hedge she couldn't wait and asked me to leave one for her. June 26, 2016
Rated 5 out of 5 by Gaslike power without the gas The power of this is HSA66 is only slightly less powerful than the HS80 and after almost 10 years of the HS80 2 stroke smell I really like the HSA66. After the first hour or so of trimming we were nearly done with the job when I was walking around looking everything over before the blowers started. I saw a bush we missed so I picked up the HSA and while looking at the bush I instinctively pulled the center of the trimmer like I was trying to pull start the HS80. My guys all started laughing and it wasn't until I looked down I realized I had just tried to "pull start" a battery power trimmer. Ya, its that similar. Batteries are a real option for professional daily use. We are starting to phase out the HS80's and do not anticipate buying anymore HS81's. May 26, 2016
Rated 5 out of 5 by Great Power and Great Battery Life I was very skeptical of battery powered equipment but after buying a new home and going solar I figured I would phase out my gas equipment. I saw all the you tube videos on stihl battery tools and finally decided to try the hedge trimmer. The convenience of instant start, no fuel or oil mixing, no spark plug changes, and no intake filter changes, appealed to me.During its first use, I used it to trim 8-9 shrubs that grow like they are on steroids and I was left impressed! The power was there and I finished the job in 15 minutes. Prior to that I was using a black and decker with a power cord that would take me 30-40 minutes because of the difficulty with maneuvering around the electric cord to cut the shrubs. I cannot comment on the longevity or durability but I think for the homeowner this tool far exceeds expectations. August 13, 2014
Rated 5 out of 5 by This product is highly engineered and has the Stihl quality I expected. I needed a hedge trimmer that was light, powerful, and of exceptional quality. Since I own several STIHL products and have owned STIHL products for many years I am very confident that the durability and quality are in every one of their products that carry the name. I wanted a battery operated trimmer but did not want the increased weight in the trimmer. I purchased the battery belt and it works just wonderful. The standard battery will trim a large amount of shrubbery without recharging. July 25, 2014
