I have the same and are working fine...just a little play in the fitting but to no affect and yes have kept the old onesMy Wipertech’s for the X3 and Grenny turned up today. The blades on the grenny aren’t too bad really but not sensational so figured I’d change them as I had to get some for the X3 anyway.
Might theow them on this afternoon.
Have never used Wipertech so will see how they go.
