Rated 5 out of 5 by does everything needed great torque ,works quickly, a little heavy although September 15, 2016
Rated 5 out of 5 by Versitile Easy to use and has many attachments. Will be buying more attachments as needed. September 14, 2016
Rated 5 out of 5 by This tool is a small beast Just got the km90 with pole saw and hedge trimmer attachments. Ran this tool for days with no issues the chainsaw attachment was awesome cut thru 6" branches like butter. The hedge trimmer even better for all those pesky smaller branches. Why did I work so hard all these years :). Buy it it's great. August 12, 2016
Rated 5 out of 5 by Awesome Product I have been using STIHL products for over 40 years and they are the best product you will ever buy, whether for home use or commercial use July 26, 2016
Rated 5 out of 5 by The best money that I have ever spent I have always been a big echo fan and owned a lot of echo products. At first I was reluctant to buy the stihl because of the cost. After making the purchase it was money well spent. The quality is far superior from other brands that I've owned. I bought the trimmer and edger attachments along with the tree saw. I was most impressed with the power the straight line edger had. I was able to edge my sidewalk and driveway in half the time. Well worth the money you won't be disappointed. July 25, 2016
Rated 4 out of 5 by Great starter product I've had the 90R for a couple of months for a small yard and I think it is finally getting broken in, starts pretty reliably. Only once have I had trouble with it not starting and I may have flooded it, after it sat for 5 minutes it started right up. I have the edger, trimmer, and broom I use for a dethatcher. Overall happy with the investment May 1, 2016
Rated 5 out of 5 by Best Kombi System period! I have owned the KM 90R for 6 years now and have never had to take it in for maintenance. Unlike other power equipment I've owned, it always starts on the first or second pull and runs until I turn it off or it is out of fuel. I own and maintain 10 acres, 3 of those acres are manicured lawn and beds. I use this tool for several hours each week.I have the string trimmer, edger, and brush cutter that I use with this power head. I am considering buying the 130R to run the pole saw attachment. I don't think it is necessary to run that attachment, I just really want another one. Having two will allow me to share some of the work/fun with my teenage boys. April 15, 2016
Rated 5 out of 5 by I could not maintain my property without this tool. I have had my KM90 for probably 5 or 6 years. It has required no repair or maintenance... Always starts and runs reliably. I have a large property and it has had a lot of use.I have the brush cutter, string trimmer, hedge trimmer and chainsaw attachments and the 4' carbon extension. All are great quality and function flawlessly. The chainsaw on a pole is the best thing ever !!My property is an acre with 300' of driveways... It is highly vegetated with huge hedges and other vegetation...I quite simply could not maintain this much cultivated property without it. February 21, 2016
