This stroller is pretty cheap as far as double umbrella strollers go, about $80, however after only owning it for 2 months the locking bars at the bottom got bent inwards. I can still open it but now it doesn't always lock the stroller in place. It is made out of pretty flimsy metal.
It is probably worth spending more if this is going to be your only double stroller. I use mine as an extra one to keep in the car and it works for this purpose.
