I have purchased three sets of AlturnaMats from Start Safety in the past year for different pieces of equipment. I am getting ready to place three more orders over the next three months for additional equipment so all of my rigs have AlturnaMats under them. They hold up great for my application, are washable at the end of the day, and are a much cheaper alternative to replacing plywood all the time. Nikki has been my one and only contact after a difficult first order online and will continue to be the only person I deal with for future orders. She goes above and beyond to get me what I need in a timely manner. The only negative I have about the mats is that I can not always get the ones I want with handholds in them, but that is something I can do myself if necessary.
