Mine is going back tomorrow for a refund
. I really love it but the back axle that the wheels are on slides back and forth - so sometimes it's too far over for the break to engage. I discovered this to my horror earlier whilst walking uphil and had to stop to get something out of dd3's shoe - whilst try to park ds20m away from the deadly nightshade berries - and realised I had to hodl the pushchair as I couldn't lock it.
Anyone else? I can't not have a pushchair so am going to have to get a refund and get whatever's in stock - and am gutted..
Am slightly relieved though - the quick release on the handlebars is exactly where I used to hold them - it's reet awkward now 
I hope it's just me
b*
