Question: What are the exact dimensions?
Document: This is a good quality product, but unfortunately was the wrong size. It was smaller than I thought it would be but that's my fault for not checking the dimensions before purchasing.
I purchased this along with the Rubbermaid small sink dish drainer and am very pleased with both. Though they do not match in color, the features of both products are well worth it. This protector is not totally flat, so things are easy to wash down the sink. The size is perfect for my double sink as well. I am very happy with both products and would recommend them, unless you are like one of my friends, and have to have everything an exact color match.
You do need to wash it off good sometimes, though - especially around the center opening where the grid gets tight - sometimes it traps food particles. Overall I recommend this.
Worked out perfectly for my needs. Measurements are accurate. They call it White, but it appears closer to Off-White or Ivory.Center hole helps for access to drain plug.No warping after 3-4 months of use.Tip: Remove this liner when draining to get all the bits cleaned out of the sink.
We purchased two of these in the color red about 4 years ago and I am now looking for a substitute for our double porcelain sinks. It fits OK and the drain hole lines up with our drain but the mats have faded, which is to be expected after this time. My problem is with cleaning the mats. They get really gross from food particles and grease in the foods and are hard to clean.
This was an impulse buy, and when I got home from the store, I discovered that this 12.5" x 11.5" sink protector was a bit small for my sink, which is 16 inches long. Lesson learned! Think before you buy! Because it is a little too small, the mat slides around a bit, and the hole doesn't line up with my drain.
This product gives you the impression that it is rigid and therefore will hold up and not sag. As soon as I put one cup or glass it tilts towards the drain. Not what I was looking for. I gave it one star so that they description is updated to explain that it is not a rigid surface, but that it is flexible.
This is supposed to be antimicrobial but only time will tell. It is just O.K. and is better than the sink protectors I have found at the local stores.
These sink mats are just what I wanted and exactly what I what I was looking for. I did do some more searching but I always come back to Amazon to get what I want.. Works every time for me.
These are great to keep fragile items from bumping against the bottom of the sink, and being slightly raised they let more water and debris go down into the disposal without having to lift it and rinse under it. I wish they'd also make them without the center opening; while conventient for using the garbage disposal like this, I have a terrible time keeping the kids from dropping spoons in the sink and they go right down into the disposal if I'm not really watchful.
