A good weed trimmer for the money

I received this week trimmer on time as promised. It took me a little while to get it assembled not that it was difficult. It has to do with my strength.. This is an auto feeder. I've never had one of those before and it worked great. I bought Black And Decker three times now. This one has less weight than the other ones with the wheel.

Perfect for my needs

I really like this trimmer. It is the first battery powered trimmer I have ever owned, and it has not disappointed. It is light weight but has plenty of power to get everything I need done. I had issues with getting the line fed correctly on previous trimmers but this self-feeding works great. The only thing I don't care for as much is the safety button that needs to be pressed in to press the trigger. It's a little awkward to use but the safety is important. Overall I highly recommend.
