[EX Q]: I ordered these for my beach wedding. It is supposed to come with a PAIR, meaning two, one for each foot. When it arrived it had only one of the two in the package. I tried contacting the seller 2 weeks ago and still have not gotten a response.
[EX A]: negative

[EX Q]: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
[EX A]: negative

[EX Q]: I immediately fell in love with the product when I first used it. I don't make frothed milk often, so it was after the return window that I used it for the sixth time and it made a small popping sound and wouldn't start. I tried looking at the packing info and box for a contact and found nothing. I'm so disappointed
[EX A]:
negative
