Review on IWONDER Discovery Cloud Wheels 120Mm - Patented Damping Foam Core, Translucent Urethane, All-Terrain Off-Road, Compatible With Electric Skateboards (Not Suitable For Hub Motors) by Derek Pape

I love the feel of these wheels and they make it so my feet do not get fatigued but the design is garbage. I had a wheel core separate from the outer runner and throw me off when braking. i contacted Icloud and they sent me a new wheel so I chalked it up to a rare fault. Then when the new wheel was replaced the next ride another wheel had the same issue. I emailed them again and said they can have their garbage back and to refund me the money. They stated the policy it to just keep replacing the faulty dangerous wheels. The design is not ready for deployment to the market and it is your life in your hands if reading this doesn't deter you. Good luck if you choose to send money to this company.
