For what I paid a warranty would be crazy. Shipping those free warranty replacements cost more than I paid. The tiles are not any different from racedeck, no offence but this isn't rocket science, its PVC with tabs to lock them in place? Underside has a design to allow airflow to keep it dry.
As for noise, you would be hard pressed to hear the difference when you cross to Dynotile from Racedeck to Moto in my garage, then again put a car in there and you wont hear anything
I have Racedeck, Moto and a few others. Its no coincidence they all have the same city listed on the box where they were made....
Take it for what its worth, I am quite happy with my tiles, in every way they stand up to the names above and the price just cant be beat
I found them on another Forum I belong to,
Tile deal! - The Garage Journal Board
Hope its not too late to get what you want, the blue and white looks great. My only regret not getting Blue and Grey. The white cleans up but I imagine the grey would need less cleaning?
Good luck
