Review on Precision Aluminum Setup Blocks Height Gauge Set with Laser Engraved Size Markings - Perfect Router and Table Saw Accessories for Woodworking Set Up (15pcs) by Jacob Diego

Everything is very accurate. There is no need to spend more. Quality item and I am very happy with my purchase. As a beginner in woodworking, my goal is to be consistent, so I'd still use them if they were a little off, as long as they were all the same, which is stupid I know, but you won't have that problem with them to have. I hope this helps someone as many of the reviews have helped me.
