Sorry this may be a bit long.
We got a babystyle oyster travel system when ds was a baby, used it tons & when he was about 1yo we noticed the chassis was cracking, right around where it folds. It has rivets either side of the crack & dh thinks it may be strengthened inside & reckoned it 'probably wouldn't give way'. It was out of warranty & i was worried about continuing to use it as ds got bigger & heavier, so it was retired to the spare room & replaced with a 3-wheeler for long walks & an umbrella fold for shopping.
Fast forward 2yrs & we r now expecting dc2.
Neither of the replacement buggies are particularly suitable for a newborn (umbrella fold not lie flat & 3 wheeler not car seat compatible, no carrycot, has freedom harness & too big to fit in my new car.)
Dh thinks we should use the oyster again since we have the carrycot & britax car seat to fit. & why spend loads on another new one. But i still have this niggling worry about the crack. What if it gives way & baby falls out? DH still thinks it'll be ok - but would you risk it????
