It's not bad but not anything great either. It's a purely amateur machine for small areas and cleaning. Don't expect to use it on 1-2 meter tall grass with dense vegetation and have it do the job... forget it! It's only good for light cleaning and small tasks. The battery is satisfactory, depending on how much strain it takes. In my personal opinion, if you want it for light cleaning, it's good, but if you want it for heavy-duty work and large areas with grass, it's better to invest in something more powerful, especially with a gasoline engine... update 9/10/23: The trimmer line that comes with the machine can't even cut paper without breaking, let alone cut soft, low-lying grass without any obstacles like rocks or wood, etc. In other words, as soon as you buy it, you have to change the trimmer line. It's not about the money, but the frustration of buying something and having to fix it just to make it functional.
