Question: What is the actual size of the mat and what color is it?
Document: I bought this drying mat to go under another, more attractive kitchen counter protector by Joseph Joseph. It fits perfectly under the attractive one which is multi-colored glass. I would suggest to  OXO that this size is good, and the mat functions perfectly, but people want nice spots of color instead of big grey blobs on their countertops.
Good quality, dries and rolls up for storage very well, nice size and color. Unfortunately the silicone causes water droplets to bubble up and blocks airflow, so still get spotting on glassware... and for glassware is why I bought it. I've tried half a dozen mats (silicone and cloth), but still haven't found the ideal drying mat for glassware. This one worked the best, but still not good enough. Would need deeper grooves or a means or channeling the water droplets away.
I recently got creamy-colored granite countertops and was looking for something to protect them from stains. I was especially concerned about the area where our coffee maker sits. I searched on-line but couldn't find anything specifically for that purpose (except in UK), but came across the OXO mat and decided to give it a try. It's working well for me under the coffee maker, and is a good size for that purpose. Additionally, it doesn't move around on the counter. The gray is a nice color for me as the granite has gray and black veins in it, plus I have pewter accents & stainless steel.
Replaced my bulky dish rack with this. I took ages to make a decision about this item, but glad I ended up purchasing it. Great quality, great size and the color is perfect because it makes it look like an extension of my sink (blends in, doesn't stand out, which is what I wanted). Easy to clean and stash away when not in use.
I'm using it as a mat on a serving tray. Provides great traction. Lays flat. Color is about what it looks like here. Very low odor.
Keeps my kitchen benchtop dry and clean now. Is also easy to wash away any dirt found on the mat. Value for money. If only it comes in white as well to match the color of my kitchen. Will definitely recommend this to my friends and family.
This is the perfect drying mat and fits most household countertops. I'm not sure if other colors are available, but I like the charcoal color since it doesn't show as much dirt, etc. I will be buying another one of these for additional drying room.
I'd love this mat if it only could be used for drainage, but I've found it just as valuable as a place to put hot pots and dishes. Too bad that it doesn't come in more attractive colors, but I don't find the gray offensive. Plus, it's just too useful to consider the color a drawback.
*there is a hole on the mat that allows you to store vertically/hang on hook somewhere.Cons:Only one color. Wish it came in different colors.The price is a bit steep.Would like an accurate rating on how many degrees it can handle. Most people will do fine setting pots/pans that have been baking at 375 degrees. However, Using the Alton-Brown method for cooking rib eye steak in cast iron at 500 degrees may be too much. (I simply put the pan back on the stove's iron grates)Wish list if OXO Good Grips is listening about future product development/enhancement:I'd like to see this product with a center-hole to use as a sink protector.
functional mat but a larger size offering would be nice as I try and cram too many pots/pans and coffee machine parts on it.
Answer: Mat is 12-1/2" high & 16-3/4" long & the color is a medium grey
