We have been running a shindaiwa backpack blower for 5 years, and an echo for 10. They do great although the echo has taken more hits than willie nelsons peace pipe. Starter cords and starter springs are all they have needed in that time.
Shindaiwa and Echo are like Chevy and GMC pickups. Same thing different branding. Many many years ago they were different, but they are pretty much merged now in the same way Jonsered and Husky are with saws.
That blower is a beast and like having a dirt bike strapped to your back. Get some 32db ear plugs and then wear some ear muffs over those haha.
