Like about 8" diagonal

I was able to get the system set up on my old TV so I could watch shows when I'm in the garage.  The problem I have is that the HD antenna is VERY small.  Like about 8" diagonal.  (Smaller than an iPad mini).  I purchased an HD antenna for my nice TV in the house, and it is much larger...  Like an old 15" monitor.  The small one in the garage does not pick up all the main local channels.  Like we don't get the NBC channel.

It is a little small. Would of been nice if it was an 8 by 10.

Small. Like too small to fit 8 pieces of each size facing the same way.

I bought this to hold my keys, wallet and phone. I though it would be 7 inches across as stated by the product description. It is a 6" x 6" x 1.5". It also doesn't sit flat on a table due to the convex bowed out leather. The rivets are also not golden-hued brass as in the product picture, but look to be stainless steel. They are silver in color. However, on the bright side, the leather is thick and supple and appears to be of decent quality.

I was in process of building a wine cabinet and needed glass racks. These seemed to be just what I was looking for. They arrived in quick time. Some of the packages were open and screws were missing from most of them, but was no big deal as the screws that came with them were too long for 1/2 inch boards. Racks are nice and shiny and look good. Most had a slight warp and are not perfectly level, but was able to use them. My personal biggest problem is that they are 16 and 1/4 inches long, not 16 inches as described. Since I was already constructing my cabinet, I now had to back paddle and redesign my whole plans on cabinet. A pain in the butt, but finally worked out a solution and completed cabinet. The frustration factor is why I only give 4 stars. Otherwise the racks are OK as long as you know they are a 1/4 inch longer than advertised.

This product is a small notebook of isometric grid paper, meaning it is meant for 3d drawings and designs. I love it, it works really well.

Despite what the other reviewer said, the dots are indeed 1/4th inch apart, but on the diagonal, not horizontal. See the picture that I uploaded. It might be slightly more than 1/4th inch, but I also don't have precise calipers handy to make sure.

Very nice. I wanted @ 8.75 inches (L) x 6.0 inches (W).
This one looks the same, but is smaller @ only 5" x 8".

These are not as big as pictured, but that didn't bother me. I simply did two across in kind of an m shape.  This was in a 4'X8' raised bed.  Other than that, these are sturdy and very easy to install. I keep them up even when I don't need to use it as a hoop house because my plants love to climb on them.

Not perfectly square. Not all the exactly the same size. They aren't bad. Probably the best price around.

These are pretty good and the price is right.  But an inch of that four inches is not ridged so the biggest thing you can zip it around is about 7/8ths of an inch.

The brackets are nice and gave an extra place to strap things down to my trailer. The brackets are smaller than I expected; the product dimension state they are 5.8 inches long, but that was for the package. The brackets themselves are only about four inches long. I wanted these to be able to tie my jeep down to the trailer, but they are a bit small for that.

works great for lighting hookah coals, the dimensions is a little bigger than i expected but still works, i think is like 8'x8' or something like that

These worked well for plant hangers on a shed door, but beware the pots need to be 8 inches to fit inside these hangers.

Very pretty.  Wish they were on smaller sheets.  These are on 8x10 inch sheets.

Even though I read the dimensions online before ordering, I really was expecting them to hold a little more than they do.  The dimensions include the key holders, so they aren't as tall as I was imagining (too short to hold a magazine, for instance) and the basket slopes out, so the effective depth from the wall is narrower than I expected.  I bought these to put in the entryway to sort the mail for our roommates.  They can only really hold a stack of mail up to about 1/2 inch, and up to about a 5 inch tall envelope.  They are a good width, though -- that part is really great.  They look simple and nice, and are sturdy.  The key hooks were soldered on a little crooked, but I bent them more or less straight.  We'll make them work.

The cubes are NOT 9 inch. The outside is over 11 inches and the inside is 9. The LED light seems like a cool idea, but the problem is that the strip, wires and battery box are VERY visible. The walls of the cube are thin and only the front profile is wide, so they look kind of funny from the side.
