BR 450 is rated 5.0 out of 5 by 37.
Rated 5 out of 5 by from Love it. This blower is awesome. I'm a home owner and has had plenty is elec blowers. The 450 is a lot of money to me but I've always wanted a backpack blower. So after 63 years on the planet I finally said it was time. Man when I got home and used it for the first time it was way cool. My yard never looked so good. Well worth the investment! I've used a lot of equipment in my lifetime but to own something like this was wasn't happening. I'm glad I bought one. It's probably more than I need but it's nice to have the extra power. Two pulls on full choke, two pulls on half choke and it's purring! Good fule mileage.

Rated 5 out of 5 by from reliable and powerful I use my new BR 450 blower to remove pine cones, leaves, hickory shells, small branches, etc.. Does an excellent job.Having several Stihl products over the years, I currently have and use:. 2 chainsaws, a pole saw, a blower, and a weed eater. Reliability and durability of all products has always been great. Living on and personally maintaining 11 acres that I keep looking like a park keeps me and by Stihl products busy. Wouldn't buy anything else.

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.
