I tried the Zapp (we have the quinny buzz) and didnt really like it. There was nowhere to store any shopping (have previously been told it tips easily if you put anything on the handlebars), it doesnt recline and felt really wobbly (that might have just been because it was the store one).
I had a Maclaren for my eldest and loved it, really easy to use and push and did everything I wanted it to do.
I am now struggling to find a smaller buggy for my youngest (nearly 2 years old). She is quite tall for her age so all the umbrella style (silver cross. Maclaren etc) mean that her feet scrape on the floor or the wheels. Have been looking for ages now for a different one! She does walk sometimes but when I do a long walk she has no chance lol. She also sometimes sleeps in the buggy if we are out and about so needs one that reclines.
I quite like the loola but we have no shops locally that sell them so we cant try one out, it would have to be a case of buying it and hoping its ok.
I am off to look at the one Alaina mentioned because the feet are far away from the wheels and floor!
