Recently gotten the Air plus 3.0, it is great to use movement is smooth, foldable compact and able to have big storage space under. The only problem now is the safety mechanism, seems to fail as it is suppose to be slide and press to close and fold up. Not sure if anyone else bought it and is facing the same issue.
