Rated 5 out of 5 by Gets the job done in a hurry This blower always takes just two pulls to start, is very powerful, and very comfortable to work with. Very happy with the performance, and after buying (and cussing at) three home improvement store cheap blowers, I should have just spent the extra money getting a Stihl in the first place! October 5, 2016
Rated 5 out of 5 by Best Blower I have Owned I have used blowers for the better part of 25 years - this is by far the best professional / homeowner blower I have ever used. The power is unmatched and the electric start is awesome! October 2, 2016
Rated 5 out of 5 by very powerful Should have invested in a Stihl before I purchased the "through-aways" from discount big box stores. Hopefully this blower will last for years to come. October 2, 2016
Rated 5 out of 5 by Works like a charm! Easy to start and gets the job done! Definitely worth the money. My first Stihl blower. September 28, 2016
Rated 5 out of 5 by Does the Job Use it on my tile roof, 1acre yard, and a lot of porches/ patios/sidewalks. One pull starting. Quick work due to power. Padding on the straps and backpack is superior. Vibration is damped to almost nonexistent. Love it so far. I had hand held a before. Glad I stepped up. September 8, 2016
Rated 5 out of 5 by Awesome machine for any size job I upgraded after having a Stihl hand held blower for 10 years to a BR450 back pack. Once I got over the learning curve of throwing the back pack on, I realized the freedom that comes with having both hands free along with an incredible increase in CFM "Power". I can imagine that this is certainly not for all home owners, but it certainly fits my "farm" use. September 7, 2016
Rated 5 out of 5 by Very powerful about average for weight. Use for large yard/farm. Has enough power to remove dried in grass from zero turn mower or rake gravel from deep in sod. Very happy. August 24, 2016
Rated 5 out of 5 by awesome blower I love it, cant wait to use it next time that there is a mess to clean up. August 16, 2016
