I have an iCandy apple for my 6 month old. It's great and suits our very rural area (no pavements). But since we have to fly quite often I decided to buy a 2nd hand Zapp as it looked small and light, perfect for travelling and suitable for our carseat.
Got one half price on ebay, and while it looks in good nick, it has arrived folded and just will not open. Watched the manufacturers youtube clips and it seems that the bit at the base that has to slide out just isn't sliding out -no matter how hard I pull it.
Is there a knack to it I'm missing?
