I have several EGO tools and have enjoyed their performance. One, 100 degree day, while using my chainsaw, my hand and arm cramped-up by the end of the day. I had just picked-up a commercial series catalog and saw the backpack. I did a little research online and decided to buy one. It works as advertised and takes a lot of weight off of the tool and your arm. So far, I have only used it with my blower, but the cord is long enough to switch hands with no problem. My next purchase may be a larger battery, now that I don't have to worry about the weight.
