To be honest I wasn't expecting this to be as good as it was. It's far cheaper than the majority of other boot liners but seems to be of similar quality with lots of extra features and flexiblity.
One thing that is not mentioned on the description is that it is also fitted with a number of sewn in velcro sections (with the other, sticky sided other half also attached) on the base, rear face and side faces. These are great for fixing the sides and base to the floor and sides of the rear boot space, especially if your boot is lined with carpet, as the sewn-in ("hook" side) velcro tabs just fix straight in place.
The rear face has a number of elasticated loops that can be hooked over the rear headrests and can be attached to the side panels using pop studs on either side. The front Boot lip section zips up at either side, which is a good idea as this prevents damage to the boot panel if you are carrying stuff to the tip.
I've fitted it to a 2011 Renault Grand Scenic, and whilst it's not quite a perfect fit, it's not far off.
Overall a great value boot liner that seems flexible enough to fit a wide range of vehicles.
