Nice product.  I had to upgrade my table saw to one that I could use this in.  If your planning on doing dado's and the like, you will need to make a zero clearance insert for your table saw, if not, you will get some chipping on the edges of your cut. Other than that, very easy to use, nice compact storage, and with the shims included you can cut to the sizes of most common plywood that is commercially available now.  Definitely a add on to your table saw that will pay for itself just in time savings, let alone not having to putty up something.  I admit that I'm not like a cabinet making company, but I am a serious hobbyist and this works well.
