Lol my ears are burning!!
I don't know if it's helps but Stroll-Air are supposedly coming here ths year and do deal a lt with UK customers, so they could be worth an e-mail to find out the state of play re them coming here and if you have any issues.
I think if you aren't constantly converting the Donkey then it's great. I found most of the time it was fine but it does involve bending down to undo and do up the clips. It's not as smooth and as easy at times as at others. I also forgot to do be clip up once and only realised after I had loaded the children in and wasn't too chuffed at unloading them again. The seat units are long but thin but you need to be sure the length fits in your car.
Being more positive, the Donkey pushed like a dream, looks stunning, the hoods and recline are easy to use. I found the seats too upright for my LO but he refused to be semi reclined either. Great for my eldest.
I did have to watch hands through doors though which was tiresome especially when one moved just as I was about to go through. With say the TwinGo or BJCMD the child is set further back so hands and legs don't tend to stick out as much.
The TwinGo is a pleasure the fling open and go. It's solid as a rock, can take three times as much shopping and pushes great too. Easy to fold and folds ith the seats on. The seats are a tad too reclined for my eldest but I only use the 3 point harness on her parent acing so she just sits upright. My LO refused to sleep in the Donkey more than a minute or so, but he sleeps well in the TwinGo.
If I didn't need shopping space then the Donkey is prettier and lovely to use. But the TwinGo (or Stroll-air) is just easier to use. But it may well not fit into your boot. Stroll-air have carrycot, car seat etc options plus an adjustable handle bar and air tyres.
Tough tough decision, but knowing what I know, if I were starting again then I would import an all singing and dancing Stroll-Air.
