Rated 1 out of 5 by from THIS WAS THE WORST PRODUCT I HAVE EVER PURCHASED This is the first time I have ever commented on a product of any brand! This battery powered hedge trimmer is a constant problem. With high hopes, from previous Stihl products purchases, this item was for residential use, an occasional user, to lightly trim hedges. NOT HARD work. Not heavy duty WORK. Unfortunately, something failed. Was it the technology, engineering and/or product field testing that failed? Even using the Stihl blade cleaning spray at $10 a can before and after each use, only ending in further gumming up the trimmer blades, and repeated trips back to the local Stihl dealer. The trimmer seems to have insufficient torque, but I'm sure their engineers know. Though the battery was fully charged, the trimmer would NOT engage the blades. This happen on numerous occasions, at different outdoor temperatures. Do yourself a favor, DO NOT purchase this!

Rated 1 out of 5 by from Battery Charge Life is Too Short Nicely light weight; however, battery charge is good for about ten minutes, according to a Stihl representative. I thought I had a defective blower because it stopped working so quickly. Found out it was the battery. It takes almost three hours to charge and only a few minutes to lose its charge. Not useful even for a quick job.

Rated 1 out of 5 by from Poor run time. Power is average, about what I expected. What I didn't expect was for the battery to die after 10 minutes or less. Should have left this on the shelf.

Rated 2 out of 5 by from Run Time Very Disappointing I own two other Stihl battery operated tools in addition to gas powered yard tools. I LOVE the battery chain saw which is a very fine workhorse. The hedge trimmer is also great and both have terrific run times. When I was ready to share sweeping chores with a blower I went to my Stihl dealer, expecting another great product. There were three models but this one was the most appealing due to ease of use and weight for this active senior woman. I was stunned when it ran out of juice in about 7-8 minutes of very light use on the front porch and small back deck. I thought I had not charged it properly so I charged it again and had a repeat experience, only a few minutes of use. The "leaf chart" on their information board is misleading, implying it will run longer than it will. I am returning this blower. I suggest that Stihl use a better battery on this blower as the short run time diminishes their fine reputation. I also suggest that they show expected run times ( maybe use the word continuous), with the understanding they may vary in their advertising materials. At the very least it would give consumers a point of comparison. It should also be made clear that this blower is for very LIGHT use and run time is less than 9 minutes.

Rated 1 out of 5 by from Battery runtime too little for 1000 square feet of light work. A nice toy but mine will not run 5 minutes doing very light work.

Rated 3 out of 5 by from Not bad for small needs Good product I I agree with the person who said that dealers need to match customers to their specific products it's definitely not for large yards
