            Awful idea
            This may be the worst design on the planet. The string that’s included is also the cheapest quality. Should’ve know the great price meant a terrible design.
            by
              Overall: Decent machine for the price.
              The rapid load is pretty cool until the springs break. I brought the first one back to the store and the same thing happened to the second unit. There is a "work around" once the springs fall out. Cut the cord/line replacement sections a little longer to allow a knot in the end. Then just loosen the screws and place the cord inside. Knots do the same thing that the spring mechanism does in holding the line in place. I love the cord/line that comes with it because it is sharp and cuts through the palmetto fronds in my yard in SC. Also, this thing is a dream to start and very light weight.

                Poor start
                I’ve bought 2 of these and both have issue starting. I should’ve learned my lesson the first time.

                  Built for power and precision!
                  High powered motor for a 2stroke. I was thoroughly impressed with this weed eater as soon as I got it. I received it during the winter months so hadn’t had the chance to test until recently and I am very happy with the product! The string adapter isn’t my favorite but it is easily replaceable with a different head style. It is lightweight for a gas powered motor as well and easy to maneuver for edging and straight weed eating. Very satisfied with this!

                    BUYER BEWARE
                    This is falsely advertised with a “rapid loader”. It only take 8 inch of line and the replacement requires plyers so it takes more time than normal weed eaters! As the line gets shorter it become useless so you have to replace the line every time 2 inches or more of line is cut off. I have never given a 1 star review for any item but this one earned it.
