We bought the Mini micro for DD1 when she turned 2. I also initially hesitated at the price but she got the hang of it very quickly & loved it. I felt happy-it is quite stable- and she happily rode it til age 5.5 when she got too tall for it & we passed it on to DD2 (age 2) who loves it. We got DD1 the micro maxi which is adjustable, lasts til 50kg/age 12. She can go quite fast but again it's really stable 3 Wheeler & she loves it. So I'm a big fan of the Micros. A bit pricey but they last.
