String long life battery very powerful. Good for my 1 acre.I bought this blower as a second one for another place. I love they way it takes care of everything. It has so much strength for a battery powered blowerThe leaf blower is easy to use and does exactly what we need around our house.This works very well and does have nice power however it only lasts about 15 min on full power.At half power it's about 30 min. I would recommend a second battery and it takes about an hour to charge between uses.First, I've got to point out that I already have an EGO stringtrimmer. This deal I got came with the blower and a battery and charger for $129. A great deal for me, it's like buying a backup battery and getting the blower for free.Now, what about this blower? It's the least powerful EGO blower. It is powerful enough for most jobs without the overdrive mode. When it in the high power mode, it's probably good enough for any job, although, the time the battery charge will last will be limited. It's definitely heavier than I like and so it's not as maneuverable as a lighter unit.I have a very large yard so having two batteries is necessary for both my trimmer and my blower. Remember, this is not a pro level blower. If you are a home user you may want to find a lighter unit. Nevertheless, I'm happy with the deal I made.Everything is good with this blower, but it needs a battery that last longer than 30 minutes. Buy a second battery or buy one level up to get a larger capacity battery.It has plenty of power. Speed is variable and the higher speed you run it at, the faster the battery drains. I find I can run it at about 3/4 speed and have plenty of power to blow leaves off my deck, porches, and driveways. Then, if there is something that needs more power, I can turn it up when I need to. There is also a boost button that will give even more power if you really need it, but I rarely have to use that. I have a huge yard, a half acre, with lots of pavement and a ton of trees, so I have a lot of area to blow leaves off of, and it will handle the whole job on one charge if I don't run it on full speed the whole time. I also have the Ego weedeater and they use the same battery so I have that as a spare if I need it. The weedeater can do the whole yard more than two times on one charge, so I have some spare battery power in that battery if I need it. Batteries charge up pretty fast too.Great for small jobsThis blower is probably the best name in the industry. 56 volt battery lasts a long time. Variable speeds with TURBO mode.Omg this is better than any blower I've seen instore! Very powerful and light weight! Totally recommend it!Pour une souffleuse avec une batterie c'est très bienExcellent battery lifeLeaf blower- very powerful- works great
