I've been using the Husqvarna 570bts commercially for the last few months. It's a beast of a blower, not for the faint hearted. It starts easily and will happily sit on full throttle until it runs out of fuel. I'm so happy with it that I found a used one to use as a backup.

I am a homeowner and after 3 years of average use the crank case motor mounts broke. Was a great product until then. It was running great then nearly stalled out and simultaneously picked up a vibration. I looked it over and found the 2 mounts broke (may be more but didn't tear into it that far), and the fan rubbed in the housing due to motor flopping about.

Out of warrantee, cost 75% of new to have rebuilt. Bad design, not enough material on the lower 2 motor mount bolts. Garbage. Not going to repair as the new parts are unchanged and it will inevitably happen again due to poor casting design.

I have the husky 570 and echo pb 760 LN both about 65 cc both great blowers but the husky out performs the echo easily except in the noise department, the echo is a low noise unit but costs performance, my go to unit is the husky but if your working around people the echo has enough grunt to do the job with ease but put your ear muffs on ....

This blower was purchased to reduce fuels (leaves/sticks and other consumables) on firebreaks to negate the need for a loader or dozer to sweep up breaks prior to the bushfire season. This blower does an excellent job, starts easy, produces the power necessary and is cheap to run and maintain.
This blower has saved me thousand of dollars annually.

Amazing power. You will never go back to handheld blowers after you try this bad boy!!
Dramatically reduces the amount of time required to blow all surfaces.
The machine Looks awesome , is very easy to start and is generally very comfortable to use. It has a 2 stroke engine. I would reccomend to anyone looking to purchase a serious blower.
