I haven't use it yet, as i'm waiting for a wet day to insert it into the ground.  I have tried other makes before buying this ground spike and it doesn't fit my washing line.
It made sense buying this, rather than buying another Brabantia washing line with a spike.
When mowing the lawn no grass clipping are inside the spike as it comes with a bright red cover, just brush off the grass cuttings and insert your washing line.  The red cover hangs on the washing line when not in use (Fantastic), also i dried my very large rug back in 2018 and it was able to hold the weight.
