Looks like a decent product, but be careful of the fine print. As in blaming poor performance of their product on faults in the existing concrete underneath (you did say your concrete is looking shabby, right?). And for sure, ask for the names and addresses of previous customers in your area, particularly those that have been in place for more than a few years. That way you'll have the chance to contact those people, and maybe even be invited over to take a look at it.
Couldn't find anything on the website regarding cost per square foot. To me, that's always a warning. As in, make sure to be sitting down when they give you a personal quote for your location.
