I was looking forward in order to find a grass trimmer with an intermediate purchase value (instead of Makita), and I guess I have found it. This trimmer has two kind of blades, one for surface grass trimming and another for bushes trimming. Once received, it was tested and performed well. In fact, for bushes trimming I have seen that the surface grass trimming was more recommended, since being much sharper and quicker to finish the service. It came with an instruction manual, only in Chinese language, what is not so good. I have contacted seller that kindly have sent me (through e-mail) a manual for a similar device, that was good enough.
