Fragility design (housing the exhaust broken on arrival). Made in a dignified plastic products disposable. A user manual with vignettes about the size of a postage stamp. Not to mention broke general basic elements mentioned in the manual (eg choke?). Is nylon cutting head disposable after use? Since there is no indication how to change the wire. On the manufacturer's site, there 's even no further information. In short, a completely absent customer service. First disappointing purchase. I do not recommend it.
