Kitchen Art 25000 Plastic Spice Auto-Measure Carousel - 4.5 oz, 1 Pieces, White

Q: Are these stainless steel? It is because lots of reviewers have mentioned that these are made of cheap plastic?

I have other kitchenart items. The satin finish in not stainless steel. It is champagne colored and rubs off easily. It is not a durable finish and the color is not bad but not good either. They have cheap products that seem convenient but are not as well made as goodcook or oxo. Most spices racks are cheap and this is not exception. The ability to pour or shake is nice, its rotates easily with low center of balance and has the added auto dial feature sets it above other cheap sets. I would also note that that all sets/brands use cheap plastic so that isn't really a point of contention.

Q: I already have one, and I was thinking of buy a second. If I just buy one does it come with the adapter to put the two together?

Are you going to hang them from the top of a shelf? If not, then the bottom of one just fits the top of the other and the two turn independently. If you are, then there is a tab and twist lock for connecting two (or more). As a note, as I am sure you have found out already, the fill lid is too narrow for most of my measuring spoons.All in all, I still like to product very much and have a fourth one waiting to be used. I hope this answers your question.

Q: I already have two stacked, could I put another one on to make three ?

I have three stacked up and they work fine. It's just more difficult to move them around if you have three stacked up. I'd find a spot on your counter and keep them there if you're going to stack three.
