Excellent value
I use these both for their traditional use in machining setup and for building models. Great for holding parts in place and ensuring square corners.

Good to Setup Jigs; However, I use these to Calibrate my Riding Mower Deck Height
The 3" side (4 used) works great to calibrate the cutting deck height of my Hustler Raptor XD Zero-turn mower. They're small, easy to store, and fast to place into position when measuring the deck. With proper tire pressure I get nice and even cuts every time.

Needs improvement
The blocks "seem" to measure out ok, and they are the same size. However, they are covered in oil!! I have cleaned them twice already and still have a oily residue on them. NOT something I want around my wood working area! Note, after cleaning twice and placing in a open tray near my table saw, I noticed that fine dust is stuck all over them! Not sure how much fun this will be to clean?? I understand they are a machined product, but they are also sold to use in a wood working shop... where OIL is NOT welcome!!I think there are better options out there!
