The battery, at least in my order, was useless. Within two minutes of spraying, it fell and I never managed to spray. I didn't expect it to be this bad..

I bought it for 70 olive trees. It does the job, not that I'm crazy about its performance, I just don't deal with gasoline engines and it's quiet.

I bought it to spray pesticides in a small area.
Excellent for its price.
The best value for money available.

I used it for spraying olive trees. It works silently and effectively, without gasoline and engine noise. The positive thing is that you can use any tank you want. I used a 200-liter tank on a farm cart. In more remote and inaccessible areas, I filled a bucket with the spraying liquid so that it reaches the 30 meters of the hose, and it worked perfectly. The battery has good endurance. I climbed a ladder to reach the higher branches of the olive tree so as not to narrow the spray beam.
