Installation was straightforward, albeit the Sikaflex managed to get into some places it shouldn't have because we also got the dust cover, and I was a bit liberal with the adhesive! I didn't realise that a set of locking pins already came with the basic kit, so had bought another pair. They are a bit fiddly to use and tbh I think they should have a bigger knob on top and little bit of wire to attach them to the frame so they don't get lost. But if they do, at least now I have spares!
But overal...
