Mainstays Kitchen Sink Mat and Sink Protector

This is a great product. Just heavy enough to last for a while but not too much. Conforms to my weird-shaped sink fine. It is actually a big bigger, but it shapes up the sink easily. I do not find any problems with splashing of water when filling the sink if I aim the faucet toward a space in the grid. Prevents my dishes from damage and adds some buffering.

Perfect fit with one quick trim!

I just purchased a new RV and was scared to wash dishes and grill in the sink without a sink protector. I ran into Walmart and saw this one and grabbed it. As soon as I got home I set it in the sink. It was just one row of circles too long so I cut it to fit and it looks like it was made for that sink. I like that is doesn't have the suction cups to collect grime and is easy to lift and rinse underneath. It is really a great product for looks and utility.

Gets a lot of use - lasted nearly a year

Second time purchasing. I can be rough with my liners, but this holds up much better than previous purchases. Fit perfectly in my double sink, no cutting down required. Previous purchase lasted nine months, only replacing because I didn't let it dry adequately and it got a little yucky looking.
