Purchased rear window curtain for a Vivaro van (passenger and driver's side). The first delivery came and two sets of passenger side curtains arrived. I contacted Vanpimps and they sorted it out very efficiently. Very pleased with the service. The product itself though took quite a while to install. The rails come pre-formed and you would expect them to be a direct fit for your vehicle, this is not the case. The rails have to be manipulated and twisted to get them to the shape of the vehicle and to get them to look right takes time, confidence and a lot of patience. The curtain material is good quality and provides adequate blackout qualities. The curtain hooks are "U" shape items and seem to be strong. (There are also a couple of spares in the installation pack). Overall these curtain kits are good value for money, as long as you have the time to install them correctly.
