I measured them on a granite surface plate with a $1400 double beam Miyamoto height gage and determined they are within 0.001in of their correct measurement in all three dimensions. Even when I stacked the blocks 3 high in an attempt to increase the error to a measurable range, they were still within 0.001in of their proper measurements. I am very happy with this and impressed due to the low price.
Surface finish is acceptable for general usage. They had some small scratches which would not be acceptable on higher grade blocks. However, for my intended usage they work fine. Just yesterday I used them to help support an aluminum block I was machining, where surface features got in the way of the vise jaws. These blocks provided a quick, flat and rigid surface to clamp the part between to avoid the surface features.
Personally, I would not depend on these blocks for professional grade measurements, nor calibration. However for hobbyists or your average shop, these are a great and useful addition. I always have at least 4 around for machine and vise setup. Due to the low price compared to a professional grade (>$100) sets, these blocks can be used for material holding without concerns of scratching, denting or damaging them.
I already purchased two sets and am thinking of ordering one or two more as they are very handy for all sorts of uses around the shop.
The price is great, they arrived fast, and the quality seems good. Takes the place of a few other woodworking tools. The only issue I have with this product isn't even a true issue. However, the packaging was mediocre at best. They were packaged in a thin cardboard box (think cereal box), and the blocks were wrapped in what appeared to be a oily, anti-corrosive paper (I hope they don't corrode into dust within a year). No protective case included (remember the low price). Amazon shipped said box in a cardboard envelope. The potential to receive a dinged/dented block is there. Luckily, mine arrived in perfect condition.
Made in China, in case that matters.
UPDATE:
So I've had these blocks for almost two years now. No corrosion, still look fine. Perfectly happy with the purchase. I initially had a pretty narrow set of uses in mind for these blocks, but I've found them to be useful for lots of purposes.
Want to see if your cheap calipers are reading right? Grab one of these and measure it. At 0.0002" accuracy, they're far more accurate than any inexpensive measuring tool.
These are cheap and they work. Keep them corrosion free, don't drop them and they'll last forever.
