Rated 3 out of 5 by from Awkward Thought I'd enjoy this item but after 3 uses I prefer having the handheld Stihl blower. Just my personal preference.

Rated 5 out of 5 by from This product has a great feature The electric start makes this equipment conducive for my elderly father to use without having to exert effort to attempt manual starting of this equipment. Only problem is I would like to purchase a hip belt to attach to this unit. But Stihl doesn't show to offer one for purchase.

Rated 5 out of 5 by from Great Blower For Professional Landscape Company I have used this blower in the summer, and winter. For a cold start the best way to go about it is:If Warm TempsPrime 7 times, Full Choke, Put on, Hit Start Button, Starts Right Up, Pull Throttle, Choke Goes offIf Cold Out Prime 7 times, Full Choke, Pull Start Till It Cranks Over, Put on, Hit Start Button, Starts Right Up, Pull Throttle, Choke Goes offThe reason that we love this blower is the ability to be working, have a customer, new client, learning crew member come talk to you. You simply shut off the machine, and leave it on. When your done talking hit the button, and your back to work. This is especially handy when teaching new employees.

Rated 2 out of 5 by from E start wont work The e start is a nice feature but the problem i am having is if you start your machine in doors and then go out side when it is below 0 degrees your e start is inhabited and then becomes useless and you still have to take the machine off your back to start it. Dont waste your money on the e start and just go for a regular old pull start because that is what you will have to do any ways.

Rated 1 out of 5 by from Meaningless electric start If you're looking for a good blower, you might be tempted to look elsewhere. Although the power behind the machine is unquestionable when you get it running, the question is: can you get it to run?Be prepared to be trying to manually start the machine and electronically starting it for a half hour or longer. Playing around with the cold and warm start to get it running can be frustrating.The machine doesn't feel solidly built, feels more like it is going to fall apart on me than not. Cheap plastics and an unwieldiness to the device doesn't make me feel confident my purchase will last.

Rated 4 out of 5 by from So far so good Decided on the 450c than the br 600 because of the electric start.On a cold start you have to press the electric start three times to start. I have moved three acres of leaves chest deep .All the features are great.So far so good .Another great product from Stihl.The shoulder straps could use some improvement.

Rated 3 out of 5 by from Could be an awesome machine So far after running 3 bottles of moto mix through the machine it has failed to start numerous times now . First the spark arrestor was clogged . The screen is way too tight . Next it was the air filter it was clean as a whistle but machine would not run with the filter in . It ran fine without it . I take very good car of my equipment . I still use an Echo weed eater bought in 1978. I think there's design flaws in this product

Rated 5 out of 5 by from Great product as usual This product is definitely worth the money ! If your on the job and have to take a call no worries, no more having to take blower on and off. All around great product
