We bought one a year and a half ago when my son turned five, and it’s been totally worth it! The lowest karting age for kids in NZ is seven, and so couldn’t get him to try those out, understandably for safety reasons. Wanted to teach him the basics of karting under my supervision and Hyper GoGo was the perfect option for us. We have long pathways around our neighbourhood, wide and meant for walking and cycling, his own karting haven! I found other more expensive karts from Segway, however the price, hard rubber tyres, and portability made this the obvious choice for us. A minor issue is the velcro straps that couple the hover board as back wheels to the kart tends to gradually misalign the back wheels with respect to the front over time, but it doesn’t adversely affect the drivability. Hope this can be fixed in future versions with a groove of some kind for the hind paddles so it doesn’t misalign, but otherwise, this is a great kart, GoGo for it! I’ve attached a video of him enjoying his gift, hope this appears in the review.
