Review on Sweese 404 104 Porcelain Espresso Cups - Stackable for Space-saving Storage by Carlos Massey

Fits my espresso machine and looks good BUT that's it! Update July 2nd: One of the cups has cracked and is leaking/unusable. See image. It appears to have a faint/thin stripe on the bottom. We have treated these cups gently and only washed them by hand. The 30-day return period has expired. So now it's up to the seller. Let's see what they do. Update July 20th: So today another cup cracked and my wife noticed it made a noise and cracked like she was pouring hot tea into it. There was no impact! I expected better build quality. The seller never responded to my request!
