Buggy boards - anyone used one?

Isaac will be 28 months when No 2 arrives and i'm thinking of getting a buggy board instead of a double pushchair. He is a very good walker but he does get tired if we're walking a long way. I just don't think we'll get much use out of a double as we don't use the pushchair much now. We have a bugaboo pram which new baby will have and baby jogger pushchair so we could always use this for him with baby in a sling.



Just wondered if anyone has used a buggyboard or uses one now and what your experiences are? How old LO was? Thanks.
