BR 450 is rated 4.9 out of 5 by 64.
Rated 5 out of 5 by from Great power. Easy to start. Used once to blow leaves and another time to remove 2 inch snow. Worked great.Back pack straps leave some room for improvement and would like a center connection strap to keep centered on the back during use. Overall great performer to date.

Rated 5 out of 5 by from Easy to start and dependable! I bought my BR450 as a replacement last fall. The BR450 is easy to start and has more than enough power for my needs. The controls are easy to use and the start cycle is well designed and efficient, usually starting on the first pull. Fall clean up was a snap and it worked well getting leaves out of our stone walls and shrubs. I have even used it to clear light snow off our cars and walk. I'm very satisfied and would recommend this to anyone looking for high quality at a reasonable price.

Rated 5 out of 5 by from Best all around blower on the market. I do not own a lawn care business but I do use STIHL products at work on the fire department. After I burned up my 3rd combination weed eater (blower attachment) from Lowe’s, I knew I wanted a commercial grade blower for my residential property. This blower is incredible! I have 4 oak trees and 1 maple tree in my front yard and would spend hours raking. Now it takes me about 20 minutes to blow the leaves (everything) into a big pile and bag it up. As I mentioned before, no lawn business, but time is important to everyone and this machine saves it. It had amazing power and the cfm’s that come out of this blower at idle are more than my old unit had at full throttle. It was hard for me to find a complaint about this product, but If I had one it would be fuel consumption. It does burn through some gas. I guess it’s the price you pay for power!!

Rated 5 out of 5 by from This product is better for smaller framed people. All we have is Stihl blowers, weed eaters and a chainsaw. When the 600 Magnum came out I thought that it was the bomb but the women I work with did not like it at all and went back to the older ones. Now that the 450 came out they love it since it seems to fit better to their body types better. I'm almost 6 foot and 225 and the Magnum fits me great, where most of them are around 5'6" and 125. The power is very comparable to the 600. Now when we hire someone new we will definetly know which blower to get.

Rated 5 out of 5 by from Great machine. Amazing power! My first backpack blower. This machine really moves some air. Wet leaves are easily moved by this machine. Needless to say, I was impressed.

Rated 5 out of 5 by from Needs a chest strap to help hold the unit! Over all I love the unit, but I agree with “Shennings” Review that the backpack straps really need a chest strap to stabilize the unit on your back! I have had the unit for about 8 months and I feel like I am constantly having to reposition the straps as they creep off my shoulders.The straps might be perhaps a little far apart from each which making it hard to hold. A simple strap in between the shoulder straps would make it lot better. Although I am very pleased with the performance and power, I wish the unit weren’t so noisy. I feel like my neighbors must hate me whenever I am using it because of the db’s but I guess that’s what gives it the performance. The blower speeds up yard cleanup time TREMENDOUSLY for me and reduces the time that I am making all the noise, so I guess the shorter cleanup time makes up for the excess noise. The BR450 is a great unit and I do recommend it, but if there is ever a backpack strap upgrade then I would suggest getting it!

Rated 1 out of 5 by from This product is a great example of bad Engineering and Quality control! I have owned six Stihl products over the last 20 years. Until this purchase I have had nothing but praise. The BR 450 broke the third time I used the unit. It lasted 5 days before it had to go into the shop for repairs. It is hard to start and so noisy you have to wear double hearing protection. The shoulder strap padding is too short and does not give good support for the backpack unit. Very disappointed with the quality and functionality of the BR 450.
