I first bought these wheels for my 10 year old daughter after a few outings she really mastered them. It's easier than skating (it also), and above it can remove them and put them in two minutes, unlike heeleys, which are heavy when you remove the rollers (we also). In addition they shine when they roll. The fact of having to ask the forefoot to immediately arrest is a big security: it does not fall once. We take them to ride around town, it turns long hikes in parts of fun, and everyone is impressed and wants to know where I found them! At Christmas I took another pair for my 6 year old son who loves too, it was easier for him than heeleys, although it also happens there now. In summary it is original, it's playing sports (the leg muscles working quite particular tibia), it's easy to put on and remove, and it's light unlike a pair of skates that I imagine really lug around in my bag for shopping !! and that's reassuring! In short I recommend!
