Rated 5 out of 5 by from Like so much the first time, I bought it again This replaces the one I bought 5 years ago. I liked that one so much, I decided to replace it with the same model. The cost is reasonable and it fills all my expectations.

Rated 5 out of 5 by from Great replacement Have a 2 cycle Ryobi weedeater going on 6 years and finally had to replace the Expandit shaft. The original held its own for 6 tough years. This replacement seems just as capable as the first. Used it the day I got it and it performed flawlessly.

Rated 5 out of 5 by from Great weed wacker! I’ve used this a few times and it works great for both grass trimming and edging. Weight is not to heavy and the battery lasts for about an hour.

Rated 5 out of 5 by from Outstanding I upgraded to this from the corded version. It was and is a great upgrade. I've had it for just over a year now and it is still great with no issues.

Rated 1 out of 5 by from String trimmer I used the trimmer once and needed to replace the line. I could not replace the line because the old line was struck in the feeder. I tried to move the housing from lock to open but it was struck. The string trimmer is difficult to work with. I have not been able to use the trimmer a second time as I cannot get the housing open to remove the struck line in the feeder.

Rated 5 out of 5 by from Sold on the Straight Shaft Trimmer This straight shaft trimmer works much better than the curved shaft trimmer I have previously used. It is easier to manage and puts less strain on my shoulders and upper back.

Rated 4 out of 5 by from Working out well. We are enjoying not having to fire up a gas trimmer. This one has adequate power and the battery is lasting 45-50 min after several weeks of use.
