Overview
I've had this buggy since the birth of my son 3 1/2 years ago and it has been fantastic. Maneuverable, stylish and good quality. I spent a long time researching what buggy I wanted and with the help of the shop assistant we narrowed it down to what I actually needed from a buggy.
I was planning on lots of walking so wanted something easy to push on a variety of surfaces. I also wanted a lay flat car seat and Jane's Matrix was the only one on the market and I don't think there is a true comparison product out there yet.

Packaging / contents/ availability
I bought my powertrack from an independent store, but they could also be bought at John Lewis or Mothercare. The powertrack is no longer available but the Slalom pro looks very similar. The actual powertrack design was bought by a company called Nurse and they sell it under their brand now. Its cheaper and without the disc break but still the same buggy. They can be found at some independent stores and I've also found them on E-bay. Its called the Nurse Dakar.
When I bought mine it cost around £500 which included the pushchair part, the lay flat matrix car seat, the rain covers for both the pushchair and the car seat, and a pram bag. I was advised not to get the matching foot muff as they were very rigid like cardboard and not very warm. I believe that Nurse are selling all that I bought for around £399 so that's quite a saving.

Use
With the matrix car seat I was able to transfer my children from buggy to car without waking them but also managing to keep them in the vital lay flat position so that their spines were supported 24/7. The Matrix takes up 2 seats in the back of the car and clips in with clips that stay attached to the car seat belts. I was still able to use this set up with my second child using 2 seats for the Matrix and one for our 3 year old's seat. We purchased an extra set of clips to have a set in each car. The baby is attached into the car seat by a single large strap when they are in the lay flat position.

Once they were older I used the car seat in the upright position both in the car and on the buggy chassis. At this stage it uses only one seat in the car and the car seat will fit a child up to about 13kg which is more than the average infant carrier. I would suspect that if you had a heavier child in you would not want to take the seat in and out though as it would be very heavy. The child in strapped in with a 3 point harness at this stage.

Once older still I moved to the standard buggy and bought a group 1 car seat (Maxi Cosi Priory XP). You can also get a rebel car seat which fits on the chassis. This is the same as a standard car seat. Cheaper but obviously not lay flat.

The handling of the buggy is excellent allowing fixed or swivel front wheel depending on preference. This is changed easily at the touch of a button. The back wheels are quick release for ease of storage - especially useful in the back of smaller cars or when having to pack lots into the car. The buggy has pneumatic tyres which I thought I might get lots of punctures in but I've only ever had one - I went over a drawing pin! It has a pump supplied which attaches with clips onto the frame.

It is easy to collapse although it does need 2 hands and although the Matrix was tricky to release from the chassis at first once I'd learnt the knack it was easy. The seat on the pushchair has a multi recline which means you can chose the exact incline for your child. It goes quite flat, at least as flat as other pushchairs on the market that are marketed as "suitable for newborns". Even at its most upright it is still fairly reclined. My son just lay back and enjoyed, but my daughter sits herself up and holds onto the buggy bar at the front.

The shopping basket underneath isn't that large but I've never found need for any more space. The disc break is operated by a hand break on the handlebar which is really useful for going down steep hills. The handle bar is adjustable at the click of a button allowing it to be used by people of different heights.
The main break is strong and reliable, even managing to hold the buggy on a hill in the mud when I fell over! I certainly have always felt confident in it.
I used a buggy board (Lascal) on the chassis when I had the Matrix and it worked really well if I adjusted the handle bar height so it wasn't in my sons way. However when I moved over to a pushchair part the hood of the pushchair made it impossible to use the buggy board. I was lucky that at the time my son was beginning to walk more but it could be a problem if you had two children close together. Although if you had them any closer together than mine (just 2 years) then you'd probably want the powertwin anyway!

Price / Value for money

Although this wasn't the cheapest product on the Market it is unique because of the lay flat car seat. Its been a dream to use and has lasted really well, especially considering I haven't treated it with "kid gloves". I certainly got a bargain as I haven't had to purchase multiple pushchairs like many people do.

Overall

I love this and will be sad when my daughter outgrows it. I know several of my friends have their eyes on it as they have seen how much use its had and how good it is. Its certainly unique in its build quality and I have no reservations about recommending it to others.
