I use them for public works mainly for road cleaning. They are very balanced and the system with the ventilated back helps a lot in long-term use. It has low consumption and this is evident from the very small fuel tank it has. When I bought the first one, I was drawn to the fact that it is made in Japan and it also has the longest warranty. The fact that we still have 5 of them now justifies my purchase. In previous ones, the valves would constantly get stuck as they were four-stroke engines. I highly recommend it as I have worked with many blowers from other companies over time.
