A few prior reviews indicate there are no instructions. Evidently the manufacturer listened to you, because my product came with easy-to-read instructions.This thing works exactly as desired. A bonus (for me) is that my rear wheel can slide into this and my bike fenders do not get in the way. For reference: These are 26" wheels with PlanetBike fenders. When I back my bike into this rack, the fenders *barely* touch the frame - they definitely don't touch it enough to make me concerned.I can park my front wheel on this rack, or my rear wheel. In both cases, the bike remains sturdy and upright. Practically like magic.I have no regrets, and I imagine I'll buy another one if/when I acquire another bike.
