I ordered 2, one for my coffee maker and one for my small espresso machine. These are the perfect size, and the 2 I ended up with work perfectly - rolls smoothly and easily. I'm knocking one star off because I had to get 1 replaced because the front wheel housing was bad, resulting in the front wheels not rolling right. But, Wayfair replaced the defective one for free, and quickly. Other reviewers have complained about the item quality, so I think this manufacturer has some common quality issues.
