So far I have labored on our 300 m² lawn with a Elektrovertikutierer, in which time and again the overload protection has switched off. The first scarifying was a real treat with the new by Einhell. The knives have an ideal distance from each other and the 4-stroke engine is purring along as if there was no resistance. From the cable clutter that is history with the unit, I do not want to talk anymore. I also have long sought and compared. The price-performance ratio is well, the apparatus makes even a high appealing impression.
