Consistency is perfect!
I use these for 3D printing projects and I have found them to be consistent in size, so much so that I can use a .05 mm gap and have it fit no problem (I like a snug fit where the magnets are encased within the project, but I don’t want to hear a lot of rattling inside).The value for money is debatable here—with neodymium magnets you’re always trying to balance cost vs. thickness…if you have a project that doesn’t need a magnet this thick there are much more affordable options out there, but for the big and fun projects this is fantastic (read: sewing notions).I love the strength of these magnets—I use them with about a 1 mm layer of plastic between it and it still feels solid as a fridge magnet or other similar projects with thick pieces of paper between the wall.Thickness, as I mentioned, is something to be aware of. You’re always going to be battling a strength vs. thickness battle, so consider that as you are purchasing your magnets. I’ve found great luck with these as I have mentioned in 3D printing projects encasing them in my project while I am printing, so you can understand only guess how versatile they may be.I will continue to buy these for sure!

Very, very strong!
Like all Neodymium, magnets these are very strong.We use them for knee point magnets, placing one on each side of the canvas and they hold your needle nicely.Be aware that for little hands that can be difficult to separate, but if you slide them between your finger and thumb, it works pretty well…

Catch me if you can
Just what I was looking for. I place these on my automotive oil filter to catch Ferris metal of 20 mg or less. They do, what the oil filter can’t do.

Very strong for their size
I wasn’t sure what to expect when I ordered these strong rare earth neodymium magnets, but they completely exceeded my expectations. These things are seriously powerful for their size. Don’t let how small they are fool you—they have an incredible grip and hold much more weight than I anticipated.

Not a good buy for me.
These magnets have great strength for their size which I love , however they fracture and break so easily I can not recommend them. If you plan to just stick them one time on something (without them snapping into place) and then never move them I guess they’d be ok. I opened the box and placed one on the table and accidentally dropped another one and they immediately snapped together and fractured. One broke in half the other fractured into a couple pieces.

Small but mighty
A bit smaller than I expected but well packaged and strong magnetic pull.
