Bought these for a beater set. They work great for general set up. These are by no means ultra precise tool and die grade blocks, but they are excellent for general shop use. They all passed a caliper check, but don't expect a lab grade product.

They perform as described. If you have never used these tools then you would not understand that they are like having multiple “other hands†lol. I will recommend these to anyone getting into somewhat precision metal working. These things are spot on with respect to dimension and thread sizes. Good buy.

Solid 2-3-4 blocks that measured dimensionally correct to .001" across all sides using a set of Mitutoyo 6" calipers. Came packed in enough preservative to survive several decades in a warehouse. No way they were rusting anytime soon.

Blocks appear to be accurate enough for my use at a low cost.

2-3-4 blocks. Arrived on time just as described. .well within .0002" tolerance flatness and parallelism.

Very precise for the cost

Great value. I always wanted a set and now I have 5. Great price. Each set is individualy boxed and each block is wrapped in oiled paper.

spent about 30 minutes getting crud and metal shavings out of the holes. Otherwise they are pretty solid appearing.update: got some of the greasey crud on my shorts. There is a lot more crud in the holes than I originally noticed.second update: spent a good amount of time cleaning them up, and they are great. I was curious and looked at prices on other 234 blocks, and realized these are only cheap cause they don't clean them up for you.

Yep they work, accurate dimensions at least for a fabricator.
