The M-Wave bicycle case is well made and looks afloat. The fastening on the luggage rack using the included material was not easy. But there was a knee pad (actually intended for gardening and the cheap hardware store available for 1), which could easily be adapted as a cushion between the bicycle case and luggage rack. The screws of course I had to replace them with longer screws. I am very satisfied so far. The volume of 17L is sufficient for small purchases, which are bound to find then to lose there place. The box rattle or wobbles. Against rain the purchased good is also protected. Previously I had a bicycle suitcase branded "Gerda", but somehow always gave rattling noises. This case "Gerda" made of very thin plastic and has broken me unfortunately some time ago.
