I got 96000 km from the originals on my Vigo in 2012.
I put Maxxiss on twice more, and got slightly less., but considerably cheaper, and the Maxxiss place will align and rotate every 10000km, free of charge.
Bought from Mothercare 20 months ago. Bht 6000. Yesterday I noticed that the foam rubber was perishing on the 'cushion'. Photos and email to M'care. Long story short, brand new one arriving tomorrow. 100% customer service.
And I have noticed that the Information Sign, asking parents to take care of their children on the steps, or not let lone children on, are quite often at the TOP of the stairs, not the bottom.
