I also bought 3 scooters for Christmas presents for my kids, 2 did not work, broken key cylinder, broken wheel clutch, I ad to borough from the other scooters to get 2 to work.  They did send parts for me to replace, however I couldn't get the clutch off the wheel, (its like they used loctite, even my neighbor a professional arm wrester couldn't get the thing off with a hammer.  Eventually they send a new plain wheel for me to again remove other parts to make that work.  I really could go on with other issues like rusted out bolts, used and scatched up battery caseings, etc... but I am just ot frustrated with the repairs and nonsenese of these cheap scooters.  I wish I would have read reviews on e-bay before I bought these.  I originally purchased scooters from costco and returned them when I saw the too good to be true add on e-bay.  At least if I kept the costco scooters I know I could have received a refund if they didn't work.  We bought the x360 which I no longer see on their site, however, I would not buy any of these.  WARNING - DO NOT BUY FROM THEM ITS GARBAGE AND YOU WILL BE SORRY.
