We have the pioneer
I got it when dd was about 1.5/2 and we loved it and will use it for this baby
It has an enormous basket, it's pretty enclosed and well shaped so unless you stack too much things won't fall out. I can get maybe half a weeks food shop or certainly a whole day out shopping and changing bag in there.
It is super easy to fold, I had some issues with my hand due to medication and so this was a big deal for me, it's very easy to do both hands needed at the same time though
I've not used the carrycot due to dd age but it seems sturdy, annoying that it has the adapter legs permanently on though so it won't lay flat on the floor if you are hoping to do that for naps.
Didn't use carrier on, I prefer a rear facing for longer seat personally and never used the carrier on with our old pram either. Adapters for seat are about £30.. Put that on top and it's the same cost as say a joie stages for instance. Just my opinion and use though
Footmuff and liner are overpriced like most others, got ours cheap on ebay, haven't washed too well and a little bobbly but nice and thick, practical and look nice.
It's light, lighter than others which is great
The downside for us is how wise it is to store, but new build home so no space designed to store either up or folded and takes up half the hallway. It lives in our boot most the time. Coming to that, you need a normal to decent sized boot to fit it. It won't fit in my mums car though hardly anything does.. Even struggled with a tiny fold up buggy. It's something to try or consider just to check.
Additionally you have to store the carrycot seperately so anyone lacking storage, like us that can be a problem but again... Like many systems
Overall, we love it. Great sturdy but not heavy frame. So easy to fold, easy to push and steer, you can feel the quality in the frame and fabrics. Parent and world facing is very important to us so loved that. Nice wheels, never struggled with it. Seat unit lovely and wide so very comfy for toddlers
I would recommend it, I've tried oyster, mothercare orb, mamas and papas mylo and mamas and papas urbo and definitely this is the best.
