Hi

I have a Mountain buggy Urban elite which i think is the same as the new jungle but not sure.
Personally i love it. I originally had a steelcraft enigma which i found steered very similar to a shopping trolley and was hard to use on any surface that wasn't very level. We are having our second in Oct 21 months apart but i plan on using a sling or having DS walk which he enjoys doing so only having the one seat hasn't concerned us (but i may eat my words)
The MB is quite big because of its wheels and takes up a fair portion of our boot which is def something you need to think about. Any of the baby shops should let you try one in your boot before you buy though.
The MB is now made by the same company as phil and ted which one of the mums in my mothers group loves the others all have MB twins, City Mini (which is v light) or Beema Q which again the one who has says is great.
Oh the MB is fairly wide but i like this because less chance of tipping and havent had an issue with supermarket aisles either
