One negative is the Blade couldn't take the grown (not too long)Grass/weeds, it is slightly damaged after the first use. I used other products (petrol mower) before on the same weeds/Grass but did manage to cut without any damages to the cutting blade.
If anyone using it to cut small to medium Grass lawns,then I would definitely recommended this to you. It will do the job and blades would last long with good maintance. It is cheaper option to other products as well.
