These are solid blocks, precise enough to create suction when placed on top of each other. Gave 4 stars because the edges are even or rounded. Over-all a solid product.

I mainly got this for sewing. they're good for weighing down fabrics and patterns so that they don't shift around while tracing or cutting out patterns.

Can’t believe I didn’t have these! Seems like every day I find myself using them! Really thinking hard about getting another set… The one with holes might be JUST as fantastic as these!

They will work, but disappointed for a couple reasons:For precision blocks- to be used for measuring, they aren't perfect.The chamfered edges aren't even, amd there is some slight deviation.Also- while I'm sure it served a purpose, the amount of grease all over them when they arrived seemed like a messy overkill.I do like the weight, a lot. Heavier than I though, which is good.Arrived quickly.

Impressively accurate in measurement and squareness. Great item to have on my maker bench along with a pair with holes for small anvil work, clamping, and critical paperweighting.

Contrary to advertisement, some edges are not beveled, very sharp, cut two of my fingers when lifting one block, painful. Dimensions/accuracy are more or less as stated. I'm only using blocks as counterweight, so dimensions are not overly important for me.

I haven’t used these. One of those thing that will sit on the shelf until I need it. But I’m very happy. Great quality.

Great value for our money. We need these to calibrate a paper cutter--our tolerance is in the .1 - .5mm range. For our purposes this set works absolutely perfectly. There's no discernible difference between the two, but we haven't put a caliper on them. They came in a weird kind of cosmoline which we removed with goof off, so they were clean and ready to go in a couple minutes after delivery and well protected during the shipping process. Would buy again.

I use them for crafts and models, nothing important. I have no idea how perfect they are, but for my needs, they are great. I have ones with holes in them, and these are heavier.

Work great. They're not a matched pair but I rarely use 123 blocks as parallels (I use parallels then). So not a big deal. Not true 1-2-3" either but flat, square and parallel which is all I need. I have gauge blocks if I need a true dimension, mainly I got these because they don't have holes to fill up with crap. And as cheap as they are if they were complete crap I would of just grinded them to match and be square, etc. I may still grind them to match later but for now they're what I wanted.
