Well, I've been using it for 5 odd months now, so now is as good a time as any to see how it's stood up to it's use. Firstly, what sort of buggy is it? Well, it's not a three wheeler off roader, it's a 4 wheeled typical buggy/pram converter, designed,according to the lady from the shop, as a city / town type buggy, with some robustness. Here's a link to one.
http://www.mamasandpapas.co.uk/range/117/Frankly, I think all buggies are overpriced and was quite willing to freecycle it, but my family surprised me my offering to buy. My main concern was that it should last, be able to be a pram and then a buggy for at least two years, and be hardy enough to recycle afterwards to someone else. I chose the black coloured one so that DP would push it as well (you can get all colors, but it's a buggy, not a fashion statement, though you wouldn't know that round here, the amount of babies with buggies matching their pierced ears and outfits. I'm not joking). He is unreconstructed like that. Also, I liked the extendable arms, as DP is tall, I am a midget.
The pram element lasted for 3 months, and would have lasted longer if Seth wasn't such a Lurch. It was easy to make into a pram, and sturdy. As a pushchair, it seems to be fine so far, with a range of back positions (suitable from about 4 months, almost flat, to upright) and is, as far as i can tell, comfy. The hood shades well, and is reversible so you can clack it on forward and back facing, negating, in the main the need for one of those overpriced sunshades. The storage is plenty for me to do a hefty-ish shop, and it doesn't overbalance with a weeks worth of recycling round the handlebars. The raincover is easy to fit and strong. The footmuff that came with it was perfectly adequate.
As for "one handed" fold down, well, LIES, but it does fold down easily, with justa two handed handlebar lift and pull on a back handle. and goes up again easily. It's not the smallest folded down, but nor is it too hefty. I can lift it, and whilst I am no fairy treadlight, I am no behemoh either.
Steering is easy and I like the swivel / non-swivel option on the wheels. It's sturdy for kerb ramming and I've taken it "off road" on canal paths and tracks through woods easily enough without bone shaking. It's easy to clean and wash down. No breakages thus far, and it's use is daily.
It also fits buses easily, crucially, the narrow corridor bits some buses still have.
Quibbles? Seth doesn't like the straps that hold him in, but he wouldn't. Sometimes they twist so a blanket covering them behind the baby is more comfy.
So I haven't turned into a pram obsessive, but this does seem to work well and do the job. It's expensive at £300+ , but then, these things are, and if it lasts well, it will have done it's work and been worth it. It's not the trendiest of buggies, but it is practical, and if you don't want a fashion statement, but a buggy that works well, it's a good bet.
