Rated 5 out of 5 by excellent product that saves you money in the long run I have about 20 trees that need trimming every year. getting it done professionally would be cost prohibitive. And 20 trees is too much work for a consumer grade pole system. With this attachment, I can reach as high as I need to go. any higher and I should call someone with a bucket truck or a tree climber.

Rated 5 out of 5 by quick connect This is one handy heavy duty attachment and is a must have....its ease of use and extra reaching ability is worth every dime. As always with stihl.....you buy once and use it for life! May 9, 2014
Rated 4 out of 5 by No more ladders, less risk of falling With this shaft extension, I don't have to climb on my tall 8 foot ladder anymore and risk injury from falling. I can keep balance and mobility with both my feet on the ground while reaching the higher hard-to-get-to spots. I use this with the HL-KM 135 adjustable hedge trimmer along with the KM 90 R powerhead and it works great! I must admit, it can get a little heavy after awhile, but that is what rest breaks are for. I compared the more expensive carbon fiber shaft extension to this one, there is not that much difference in the weight when you operating it with HL-KM 135 (they both get pretty heavy after holding it awhile). At least not enough to justify spending twice the amount on the lighter version. July 14, 2013
Rated 5 out of 5 by Must have with saw attachment I purchased a km 130 last year with trimmer head blower and pole saw attachment I have been very pleased with all of it thanks stihl for excellent quality and power. Recently I was needing to cut some limbs that were a little out of my reach so I ran to the local hardware store and looked at extensions they have two options this extension and a light weight version at nearly double the price. I went weigh the less expense because to me the couple pounds less weight wasn't with the money. This extension and the saw are two feet shorter than stills extendable pole saw but is much cheaper and can be taken off and the kombi unit used for many other projects if anyone needs to know the adjustable saw is 13ft overall length and the km 130 with extension and saw is 11ft but for the versatility and mint savings I think I can dig out my step stool if I need two more feet March 31, 2013
Rated 5 out of 5 by Nice to Have I use this with my chainsaw attachment. With out it that attachment really would not help me out much. This is a must have attachment wit the Kombi chainsaw atachment. January 15, 2013
