I contacted this company in late spring, due to the breakdown of my brand new XIAOMI electric scooter. I've only ridden it a few times, and it's already broken down. I was disappointed. The specialist from the eco-service repaired everything in a day, and did not take money for visiting me, and for inspecting the scooter. He gave me some good advice, and gave me a guarantee for a whole year. Of course, there was a small disadvantage, it was difficult to contact a specialist, but the result made me very happy, excellent service!
