I wonder if anyone has any experience of wood laminate flooring.

We have a concrete floor, so 'proper' floorboards are out (without
putting batons in and stuff). We have been looking at the wood
laminates out there - some of which are very good and some very
expensive.

The typical ones seem to be 15mm thick, and for single plank are above
our budget. (Single plank is a particular bug-bear of mine as I think
the narrow strips look like laminate!).

However there is a Kahrs product which is only 7mm thick and is about
£22 a metre and looks really nice. As I understand it, the only
downside of this is longevity as you can't sand it down and re-oil.

Anyone any experience of these thinner products? Is it just false
economy? Or should I get over my aversion to 3 strip?
