Rated 5 out of 5 by from Awesome buy ! Bought this in Spring time wish I would have done this a while ago. It cleans up sidewalks and driveway fast. Be interesting to see what it does once Fall time comes around.

Rated 5 out of 5 by from Without a doubt the most powerful blower I have used I bought this to help out with all the leaves and pinestraw I have to clean up every year. Best tool for the job without a doubt. Blew my entire yard and had a pile two feet high and this blower was still pushing the pile. I was also planning on dethatching my lawn. Well thats not necessary anymore this blower took care of that. If its not attched by the root its gone. Great investment if your tired of raking like I was.

Rated 5 out of 5 by from Product is very easy to operate Blower 450 makes hard jobs seem easy, starts easily, runs great and is very powerful.Really like the extra large fuel tank and the extra year warranty offered for using Stihl synthetic oil was good idea. I would recommend the 450 to anyone needing a powerful blower

Rated 5 out of 5 by from Should have bought years ago! I've never owned Stihl products before, but I'm a believer now. I'm I've had a hand held model for years and it gets heavy and isn't as powerful as this. We have about 1/3 acre and it does great with all the trees and leaves we have. I can use it all day no problem unlike my hand held by a different manufacturer. Starts real easy. I love the "cruise control" feature. Set the level of blowing power and then I just walk around the yard doing my thing. Less fatigue on my hands and fingers compared to my old hand held. My only concern is that I should have bought it years ago!

Rated 5 out of 5 by from Unbelievable Have been using a Stihl handheld blower for years and finally bit the bullet on the backpack. It is so much more powerful, which allows me to accomplish my work so much faster and more efficiently (I have five, yes five, sweet gum trees and those balls are a pain-this new blower makes clearing them so easy). It was also powerful enough to blow out my downspout and underground drains, which have been partially clogged for a long time. It starts easy and works just like a Stihl and did not disappoint.

Rated 5 out of 5 by from Wow. Best purchase I've made in a long time After using a hand held blower for uears to clear fall leaves, I decided to take the plunge and purchase a back pack blower and what a pleasure. I compated similar units from other manufacturers in use by my neighbors. All had their plusses amd minuses such as noise, power, comfort, price, etc. The Stihl met or exceeded in all categories. What a pleasure to operate.
