The distance used over the year and a half is approximately 500km. It was used both indoors and outdoors, so there may be some pet hair (dog) attached from outdoor use. I noticed when taking photos for the listing, that the part that fixes the front fork is slightly tilted. This can be easily adjusted by yourself, and the instruction manual states that a deviation of about 3 degrees to the left and right is within the acceptable range. Also, there are two small holes near the red screw on the front fixing part, and one of the small pins (screws) is missing. However, this is just an auxiliary pin attached to the outside, and there is no problem at all with the use of the main unit.
