BR 450 is rated 4.8 out of 5 by 72.
Rated 5 out of 5 by from Ease of use I have known of Stihl products for years, but this was my first purchase. The starting features of the blower make it one of the easiest to start and it runs like a banchee. It easily removes leaves out of the river rock drainages. It has great controls allowing an infinite speed control.

Rated 5 out of 5 by from This product is everything I was looking for in a blower. The BR450 is an absolute powerhouse blower for any homeowner who needs that kind of horsepower. A job that took me 3 to 4 days by hand to do was accomplished in 4 hours with the 450. A word of warning to smaller home owner men. This blower is a little on the hefty side and would actually cause you to expend energy just to keep it pointed straight out. But the results from the use are totally worth the effort. I would rather spend the money to buy the tool and do it myself than pay someone to do it. Especially with the outstanding results I got from using it. I have 2 acres of manicured lawn in the middle of the woods with overhanging limbs so yes, I need that kind of power. And I got it.

Rated 5 out of 5 by from Easy starting & hard working Replaced a 25 year old BR320 backpack blower that was getting cranky when starting. The BR 450 gets the work done far more quickly.

Rated 4 out of 5 by from Overall - very satisfied - I purchased this blower for year-round residential tasks. It is used for clearing debris and for moving light snow. (I have also used it to blow water off my truck after washing it to prevent water spots.) The adjustable power allows me to clear a stone driveway without blowing the Modified 2B away along with the leaves and snow. I do find I can reach the end of the power band easily, but I can usually complete my task effectively using less-than full throttleThis model was chosen because it is designed to run for extended periods of time; it has done so very well, for me. I think I get about ninety minutes out a tank of gas with varying throttle speeds.I would like it if the hose storage design was developed beyond just a piece hook and loop to hold the hose upright against the carry handle. The shoulder harness needs a chest strap to help keep the blower from moving, especially when working on and angle or un-even ground. Lastly the "choke" nozzle should attach to the hose either with a better twist-lock connector or a latch that provides a positive connection between the nozzle and the hose. However, I do like that as a part that will see wear, it is replaceable.This is a very good purchase for me and I expect it to perform well and last as long as the other Stihl products I have purchased.

Rated 4 out of 5 by from Great Backpack blower All I can say is excellent, except for the shoulder straps. Everyone that owns this unit has the same complaint, and should have been solved by now! Used it last night and had to use my left hand to hold both straps together the entire time. When I let go, the left strap comes off my shoulder.

Rated 4 out of 5 by from Good value for price. Good machine. But I wish I had bought a bigger one.

Rated 5 out of 5 by from Great overall blower Easy to start, plenty of power to blow grass clippings, sticks and wet leaves. Will move large piles of leaves even at 15-20 ft away. A great unit for large yards or commercial use.
