Bought this trimmer about three weeks ago and used it for the first time this past weekend. I have approx. 1/5 acre in the city so thought this would be an appropriate size for the yard. I am switching from a gas trimmer so I didn't expect it to match the performance but it was ok and lighter also. I made it about 3/4 of the way through my trim job and the battery died, not what I expected from other reviews. The problem being, it is not variable speed as per the description, it's either on or off so it drains a lot of power on light cutting. It seems well built for the price and found the bump feed worked well, just not impressed that the description is misleading. Now have three options, return it, buy another battery or wait for a re-charge.
