WorryFree Gadgets Hoverkart Go Kart Conversion Kit for Hoverboards - Safe Kids Ride for All Ages & Heights - Universal Compatibility with Most Self Balancing Scooters (Hoverboard Not Included) - Perfect for Backyard Fun, Neighborhood Cruising & Outdoor Adventures

Kids love this thing. Definitely adds a new dimension to the hoverboard. Instructions are not that great so I’ll save you much time and aggravation with this one simple tip for attaching to your hoverboard. Turn it upside down to attach with straps.Excelente producto a mis niños le encantoDon’t know how well it would have worked because I never completed putting together together the kart. I didn’t check every part before I started putting together.So when I came to the seat, I noticed a crack about 3 inches in the back of the seat. The seat looked made of very flimsy plastic. I returned it to be exchanged with another one. Unfortunately this is the only product I can find that will fit my grandson who is a small kid.I ordered four of these as part of Christmas present for my grandkids to go with the hoverboards. so the concept is great and it is so much fun for about 4 hours total.....until the velcro breaks. The seat works fine but the velcro that holds the seat to the hoverboard breaks and then is pretty useless. This happened on all 4 of the chairs. I contacted the customer service...which is not especially easy....and just wanted to know if it is possible to order replacement velcro ...i am willing to pay for the replacements....but I have not heard back from them. So what the heck do I do now???Great kids love itBought for my kids, but it seemed to stop working properly after few daysbrokenStraps broke while my son was riding it sending him flying off and hurting himself
