Sorry to say these grommets are too small to fit over my shower curtain hooks. These are the hooks I'm using:  https://www.amazon.com/URBESTMills-Metal-Double-Shower-Chrome/dp/B0108HVDX2/ref=sr_1_11?ie=UTF8&qid=1498508036&sr=8-11&keywords=double+shower+curtain+hooks

Look nice but look more like 3mm than 4mm.  Very small crimp covers.  I don't know if I'll be able to use these.

These are very small. I really wasn't able to use them, they don't fit my chairs. I had checked the listed measurements but they are not true to what they say. Since they were shipped from overseas, it wasn't worth trying to return them. The fabric is nice, and fun color. Maybe you have smaller chairs than me.

Cant really use grommet style curtains because there isn't enough room between the rods. I had to by other style curtains, which I don't care for.

Sadly the size was wrong and won't work for my application. It was unusable.

This is only good for installing eyelets for shoes and craft projects. I knew the grommets would be small, but I had expected larger grommets than I received. I am keeping this tool, because while it it is not suitable for my intended use, I do enough small projects that this will perfect to use.

FYI - the grommets are bronze. It will work for us but I wish I had know that before ordering.

They do not work with 8mm plastic push pin retaining clips.  Also, the rim of the grommets are not wide at all so if you are looking to cover a larger hole these will not do.  I did not see specific measurements when ordering.

I am very disapointed!
 These looked so good...Reception is excellent, sound is above average for these types of head gear...BUT....They are just too small to fit me....and are so small that I bet most full grown men will not be able to wear them...Certainly not over a ball cap as many of us use them.
  I have now gone back to my old smelly beat up Peltors....Which still work well and fit with some extra room to spare.
These units are so small that the lower strap broke when I tried to fit thyem over my ears..
What a shame....Ruined by some engineers attempt to save 3 cents worth of plastic in the head strap.
WARNING...IF YOU WEAR ANYTHING LARGER THAN A large HAT SIZE THERE IS A VERY GOOD CHANCE THESE WILL NOT FIT.

I had rated as Excellent quality based on purchase of Glasfloss in another size from another seller. Based on that experience, I stated previously that they were better than the well known brand the box stores carry locally at half the price. They probably are good quality, but I cannot use due to sizing problem.  I had extras and did not need to install these until much later. When I did, I discovered that they are too small to fit. I am past date to return per seller so I have 12 filters that are labeled 24x24 but leave gaps on all sides. Previous brand used labeled 24 X 24 fit. I can't use these.  Carefully read exact size and measure before ordering in quantity. Do not make the same mistake I did.

I bought these for a laundry bag drawstring, but they wound up being too small. Can't use them. Return shipping is more money than what I paid for them.

The only real problem with these are that they are too small, so now I will have to try to search for some extensions.

The size isn't adequate for most of my quilting projects so I suppose that would be true for others as well.

I could not fit the chicken wire shade to the electrical connection.  The threads were too short to allow the connection to be screwed together.  I am returning the product.

The mats were the correct size and fitment, but the grommet for mat peg to keep it in place is about 3x the size it should be.  It doesn't snap down or anything, just loose lays over it.  If I would have known about this I would have purchased another brand.  Aside from that though the quality seems good for the price.

They were a great product but did not fit the project I needed. Customer service was great when i needed to return. These are pretty small and did not allow many papers to be secured! 1 Inch size was much better.

These might be okay,  but they are too small for the size indicated.  They are going over a pair of muck boots and must be designed for shoes so they don't stay on.
