Summary: We have the G Luxe and a Vista are very happy with them both. There have been issues though. The G Luxe can be unstable given it's design especially when there is a diaper bag attached to the handles. This can cause unwanted tipping when your child is out of the stroller. There are also some sharp pieces of plastic on the latch that keeps the stroller locked closed.
Summary: I've been using a borrowed Maclaren Quest for the past few weeks as I waited for my G-Luxe to arrive.
The general quality of the stroller seems cheaper, but at ~$100 less than the Maclaren, that seems reasonable.
Summary: I was quite excited to read the reviews on this as they were all extremely positive. I ordered without hesitation, and whilst the claim that it is lightweight and easy to put up and down are both very true, those are about the only redeeming qualities. Its very small and narrow - my little one is 18 months, and he just fits in it width wise, but he doesn't look hugely comfortable. The device to recline it is a drawstring and is to be blunt... RUBBISH.
