You can lock the handle in several inclination levels, thus providing large and small users the optimal handle height. The wheels are sturdy and large enough for normal lawns.
The front yard of our house was the first site. Probably never scarify in the last 50 years, there was a proliferation of mosses, which occurred in the shadow areas especially.
The scarifier has the ordentlch raked in the first stage and a surprising amount taken out of the "lawn".
The double benefit is this machine that with two Allen screws to (key is attached to the unit) can replace the roll with the blade against a fan roller which has many small spring-loaded needles.
The aerator cylinder does a great job.
Overall, I am satisfied with the device, especially since I am amazed at the maneuverability and ease of handling.
In price / performance ratio Einhell scores clearly here.
