I have an older EBZ7100, which I would guess is roughly equivalent to the EBZ7500 Redmax makes now. Every Autumn I clean a grassy area that is completely surrounded by woods, full of oak and pine trees. The pine needles are just awful on a blower and are very difficult to untangle from the grass and move across the yard. When I used to do it by hand with a rake, we would get about 40 to 50 large wheelbarrows heaped full of just pine needles, depending on the year. The leaves were over and above that. It would take two people two full weekends to do the clean up by hand. With the EBZ7100 I do it alone in just one weekend. Two days, sun-up to sun-down, and it does a better job than raking it all by hand. There are sometimes where I think I should have gotten the 8100, but like you mentioned it's quite a bit heavier so it’s a tradeoff. The 7100, does really well and it’s a bit lighter. I watched those electric blowers on the YouTube videos posted earlier. That is nothing in comparison to the performance of my blower. We also have an older Echo hand-held blower, and an older Stihl that was made before government regs. were enacted that neutered the handheld blowers. And even those are much more fatiguing to use and have nothing like the power of the backpack blower. The Redmax is much nicer to use and is much more powerful. I have to agree, one of the best purchases I've made.
