Rated 5 out of 5 by from Great Leaf Blower I use this blower to manage 3 acres of land with large maple trees that cover the entire property in the fall. The blower works great and handles the large volume of leaves with ease. It has great power and runs well, it can actually blow around the 3/4 round rock i have if I'm not careful. I am only on my second tank of fuel so I cant rate the dependability but so far it starts right up and gets the job done well. If you purchase the STIHL synthetic premix oil (you will need it for your fuel anyway) STIHL will double the manufactures warranty. I'm not sure how long this program will last but its a great value and piece of mind.

Rated 5 out of 5 by from Best affordable bp blower there is My work has the magnum 600 series & they work flawlessly, but as your average homeowner I wouldn't need that kind of power & price tag. The 350 seemed too small for my 5 acres of woods so I then narrowed it down to the 450. It's by far the best value for the price. It's lightweight, I can comfortably & safely get on/off my roofs with this blower. comfortable, I feel no backaches after wearing it for any length of time. powerful, I can blow heavy leaves with ease at 10 feet. quiet, my ears don't ring after prolong time at full throttle. & it runs long on a tank of gas. If you have any doubts. You cannot go wrong with the 450.

Rated 5 out of 5 by from Impressive The 450 blower has saved me tons of time. I originally thought the tiny choke knob would be a problem, but so far, so good. Disclaimer- I’ve only burned through a gallon of gas.

Rated 5 out of 5 by from Marvelous Machine! I have owned and worn out several electric blowers and big-box store backpack blowers. The Stihl BR450 is the absolute best I have ever had. The idle speed air flow is great for cleaning my gravel driveway without blowing away the gravel and the high speed, when needed, is absolutely awesome! This machine cleans much faster and cleaner than any I have had before. However, it seems a bit heavy. A chest strap.would be most desirable to keep the machine balanced. It tends to slip off one shoulder after a little while.Otherwise, it is GREAT!

Rated 3 out of 5 by from I'm on the fence with this When I first started using this backpack blower, it was awesome. Slowly the power drifted away and was getting harder to start. It always started up on the third hit of the starter switch...always. I took it in to the shop when it finally was so bad it just wouldn't rev up and here the spark arrester was clogged...after just a few hours of total use. I always run it full tilt and it doesn't idle long.So after dropping some cash to find out that's the problem, it still doesn't start up as easy as it used to when I first got it. I'm considering taking the spark arrester out completely since it's used in a home environment and there's no chance of fire. What a ridiculous design that we have to keep swapping this thing out. I can see these screws getting stripped after a few de/installs and having to replace those as well. Bad shoulders led me getting the auto start version...time will tell if I made a bad decision but it's not looking good for the long haul.
