Although I do not complain about the use and lock of the main body, I think that there is no need for strength fittings in addition to being insufficient in strength.It is bent easily with just a little tightening and the attached bolt / nut is also bad, so the screw thread collapses I think that it will be hard to install if it is a bit more rugged and not long.
Although the product attempted to be attached to the scooter but the attachment screw of the attachment included only three pieces of M6 where there were four screws, one screw of M5 was included. Besides, the shape and length of the screw are different. What was the person who stuffed the accessories such as the screw nut washer though it was a different screw just looking with the eyes? I bought a screw and went to a nearby home center for troublesome work to get it replaced.
There was a problem that the lid did not close properly to the item that was sent first, and it was exchanged. The next sent item seems to be usable without problems. I appreciate Mr. Monotaro's polite response.
