I've used these floorboards in two rooms. I'm very happy with the
results but I found that the quality boards varies a lot from one batch
to the next (inaccurate machining, missing knot cores, shipping damage
and severe warping).

I ended up visiting several branches of Wickes to pick the best boards
from each to get enough for a 5m x 4m room.

How consistent was the thickness and T&G machining? ie. any steps
