Good day,
I just wanted to briefly share my thoughts as well, professionally installed flooring with master products I actually find quite good.
We are currently installing Lindura 400 HD Oak for a customer.
It cannot be installed without special tools / saw blades, normal jigsaw blades do not hold at all, they become dull immediately, carbide-tipped circular saw blades do not work well either, they also become dull and smoke right away, we are not familiar with this, no idea what kind of carrier material this is, diamond tools are required, who normally has such things as standard tools? One should know that.
I can't say much about the quality yet, the whole thing seems very sensitive to us, also not sustainable, when the floor is old and worn out no refurbishment is possible by sanding and re-oiling.
