I've had this set of blades for over a year now and am very pleased with them.  I use them on my Delta Unisaw and they work great.  The most freqent use I get from them is making dados in plywood or hardwood cases for plywood shelves and dividers.  The adjustability with the various blades and shims helps me to match the groove exactly to the various widths of my sheet stock.  The bottoms of the dados are very smooth.  Not router bit smooth, but perfectly  acceptable for fit, finish, and glueups.  They make very clean cuts and I have seen almost no tearing or chipping when cutting in veneered plywood.  In a pinch I had to use this set once on a project that used green treat lumber.  They tore through it with ease, and most importantly kept their edge.  These are very high quality blades and should cut great for years if properly taken care of.  I store them back in their hard case with the supplied dividers between blades after every use, so they still look like new after many hours of use.
