As always, your review is too professional. I believe your review can help more hesitant electric skateboarders. To be honest, you rode in the heavy rain and Veymax Cejour survived, which is beyond our expectation, but we are very proud of it. We had very high requirements for the waterproof ring from the beginning of the Cejour design, and today it has achieved the results we wanted. Thanks again for your review of Cejour!
