I threw away a Costco faucet that was in my kitchen, too many complaints from everyone that used it.
I hated it too.
My son installed a Costco disposer for a customer that was pretty cheaply made. I won't install those anymore. I say that because the last one I worked on had such a small inlet for the dishwasher that the air gap would leak over the kitchen counter. I would say that the drain hole was a little too small.
I looked at the WaterRidge when I was doing my regular shopping.
It looks like the standard builder grade stuff that I normally replace.
You won't see me selling something like that. One of the things I look at is the trapway. The WaterRidge has some pretty tight bends. The trapway may work for a while for "some" people. But eventually those bends will collect things. And those "things" tend to hang up paper.
There are no hardware stores that carry parts. If you need parts, keep the 1-800 number and the original paperwork. You will need to get parts from whoever supplied the container shipment. There is no manufacture called WaterRidge. That's a name that Costco slaps on generic product that the buyer picks up. Keep the paper work. If you wind up with an orphan, at least you weren't out much. As a installing contractor, that type of thing would drive me nuts; not having parts handy. I am afterall, a guy that loves fixing things. You need parts to do that.
I'm not liking this trapway. If you don't need much, then maybe. It's looking pretty small to me though.
