I bought this a week ago and lawn trimmers before yesterday had in use. The engine is sufficiently strong and made it even 30 cm high, dense grass and weeds no problem. After about 60 minutes using both my arms have ached. You would not believe how difficult such a device can be, when to use it a long time. The relief could have been designed differently, because me the plug of the extension cord is tripped repeatedly. The assembly of the trimmer as sold is simply u. To accomplish for everyone. The drawings in the manual for installation of the plastic protection are drawn incomprehensible and very small. The device can be put in all necessary positions can in this respect nothing to be desired. The plastic cord on the reel, however, is grown to high demands and often needs to be adjusted, but this works very well. Overall, I can for this grass trimmers give a positive review and I would buy it to me again. (Nothing is perfect!)
