This product may be a little high in price, but if you plan to have it for a number of years it is worth every penny. My last backpack blower is an echo model which was marketed under a lesco name. It has lasted more than 10 years and still works fine.
I needed a blower that could do the job in a quarter of the time. The Husqvarna 580 BTS is a beast. It took without exaggeration about 20% of the time the old blower would take for the same job. It starts immediately. So far I'm impressed. The only drawback
is it may be a little heavy for some people, but its perfect for me.
