This is by far and away the best quality rotary line we've ever had.
The spike fpr example has stabilizer fins and plastic bung for when the line is removed - very thoughtful additions. 
The height adjustment mechanism is superb - very smooth easy operation.
Little extra touches like a cover zip, and a quality peg bag clip - all add to the overall impression.  Crucially, plenty of room on the line for the biggest sheets (and well off the ground).  The instruction leaflet is clear and informative.
Very well packed.  Overall 10/10 and a Gold Star.
Slight downside - delivery.  A couple of weeks.  But being the winter 
there was no hurry anyway.
