I'm just a worrier. Sounds like it's better than I gave it credit for.
The clicky stuff was very sweet to lay - it was just in summer that I saw
some hairline gaps open at every joint on cooler days. They weren't ugly -
but I just remarked to myself that they might be scunge traps if in a
kitchen.

I helped fil lay something similar in his conservatory and you can at times
notice hairline cracks like you describe. Not noticed them in my kitchen -
and the joints are slightly different. Maybe they have improved it a bit.

In every other respect it's excellent stuff. Hardwaring (if you got a
quality brand) and very quick to wipe off.

I suspect this maybe the answer. You get what you pay for (usually...)
