I would give it 5 stars if the instruction described clearer. It took me a while to assemble it. The hardest part was figuring out how the straps went around the hover board. The wrench and tools came with it did not do the job very well.
It was very comfortable to ride on. The shock absorption does its job very well. I have no problem go on and off the sidewalk edge. The front wheel needs to have a fender to stop sand blasting to the face.
