I have one and I love it!
I will give you the positives and then the negatives, but first will just quickly describe how I've used it. Sorry for the essay!
I live in a smallish town and don't drive, though my DP does and also occasionally we (ie me & DS) have days out with my mum, or get lifts from friends etc. We have a very small house and I tend to store it folded up in our hallway (which is literally about as big as the width of the front door, squared). I have used it as my only pram/pushchair up until 11 months with my DS (born Oct last year), we have just bought a lightweight buggy for a holiday.
I use it most days for walking in town, haven't really used it off-road much as it is quite hard to push on rough ground. However I'd recommend a sling or soft structured carrier such as the Ergo if space is an issue, as you really need a 3-wheeler if you are going off-road a lot and they tend to be bigger and not so good in town.
I also use it on buses and it's fine for that - but when we were in London on holiday I was glad we had the lightweight stroller as the buses there were really packed and there were quite often more than one on a bus at a time, which is not the case here. I have folded it once to get onto a bus but you can't really do it one-handed so you need someone to hold the baby!
Ok positives:
The seat positioning is perfect, it has 4 recline positions (upright which is good for after about 6 months, flat which is good for newborn, almost flat which is good for bigger babies sleeping and about 45 degrees which is good for the 4 month old who can't sit but wants to look at you more) and obviously can face you or away which is great.
The seat looks really comfy. I had no problems putting a newborn in it without bothering with the carrycot. It has adjustable suspension as well which helps!
The seat fabric is reversible which is great as it feels like you have a new pushchair every 6 months! The summer one is nice and breathable as well. Also, it washes really well at 40 and dries very quickly.
You can recline/sit it up with the baby in which is useful.
I liked that you could fold it either together (facing either way, it also remembers the seat position which is useful) or separately so if it's too big folded together you can separate the seat part out. The chassis is light enough to lift one-handed when folded but with the seat on it isn't.
The switch to change from swivel wheels to locked wheels is on the handle so easy to use if you are going from rough ground to smooth, or if you want to rock it back and forth.
It folds umbrella-style (into a long thin shape) rather than flat (as most first pushchairs/travel systems do) so it takes up much less room and isn't too awkward to carry. It's actually quite small for a travel system type pushchair even though the seat is big! So easy to get through doors etc.
Apparently it takes a buggy board very well as well if you are planning more DCs.
Okay negatives (I like to read these to see how much the problem would annoy me!)
You have to take the hood off to fold it.
The raincover is a bit fiddly and annoying (it zips onto the hood so you have to unzip it or just fold it back and it doesn't have anything to clip onto when not in use) - I thought this would annoy me more than it does. You can always get a universal raincover if it's really bad. The plus side to this is it's really compact when unzipped compared to other raincovers and takes up hardly any space in the basket.
The harness is weird and you have to hold both sides together to clip it in (in other buggies you can clip one side in at a time - which makes things easier if your child decides they Do Not Want to be strapped in!) - I decided to attach reins (there are D-rings if you want to do this) as a second harness and I use them when DS is awake and the original one when he is sleepy. I also found because of the harness he is quite restricted with the original one on - good when little, not so much when they are older and want to lean on the bumper bar to look around.
I find it heavy when folded up. It would be fine if you are just lifting it in and out of the car/just out of the front door but if you live somewhere with lots of steps or you are likely to need to fold it on buses etc often, I would go for something else. Having said that, we live on a huge hill and have steps from the street to our house and I have managed fine!
Finally your question, is it easy to fold - I find it very easy to fold and unfold! Despite forgetting totally how to do it in the car park the first time we went out with it - I do think it's a fab pushchair, especially for the price. If you want any more questions answered do ask!
Oh also (one last thing lol!) if you are thinking of getting the compatible carseat, get the Maxi Cosi if you have isofix but the BebeConfort Creatis Fix if you don't. They are both compatible. Don't use the Windoo carrycot in the car, it might be legal but it isn't very safe.
