I've had mine for 10 years - couple engine transplants - 10 years of tracking / DE
Has held up well
I should probably replace a few tiles that have been drilled through or been melted with a blow torch
BTW - I did the bigfoot tiles from Greg Smith Equipment. They had the best price and honored one of the rates I saw on ebay (turned out to be less than 1/2 price of racedeck)
