Our son got the scooter at Easter. Since then we can finally walk again without hearing "when we are finally here ?!". We opted for the version with the big wheels and are completely satisfied. Even gravel paths are no problem. The big wheels are a little faster and the Roller "hops" not as strong as with the small wheels. He runs "round". The quality is also very good. Stable and safe. Folding mechanism works fine, but you can easily get your fingers caught! All in all a very good acquisition. Not exactly cheap but quality just comes at a price. At Amazon, incidentally far and wide at best! Then comes even include free shipping and within 2 days in`s house. So we are completely satisfied.
