Yes, it works VERY well.
Fitting is easy enough, but you really need to take the rear wheels off to do up the bolts properly.
It goes under an "Easu Up" hood without any problems.
To properly access the luggage space you need to lift up the back edge of the hood, but it doesn't otherwise get in the way.
Looks? Subjective: I think it is OK, others don't like it.
Here it is from the back:
And from the side, you have to look hard!
I may take it off when it is hot but most of the year it completely stops the cold wind hitting the back of your neck. the only downside is that the back of it gets filthy from road spray. If that is a disadvantage...! It wipes clean.
