YANG-YI no longer has any products listed for sale, based on this we assume that Amazon.ca has taken action and very likely suspended them. Reading most up to date reviews will have more details about customer frustrations.
If you have already placed an order, but since realized that your product is likely never going to come try contacting the seller on Amazon.ca. If the seller is not replying, read on what to do if you were scammed.
Unfortunately this product did not have the nose piece as indicated in the description and it is very rough and uncomfortable. I'd rather wear the disposal before wearing this. Very poorly made.
Item didn't arrive until months after expected delivery date. It was a cheap, thin, wholly inadequate imitation (without noseclip) of what I ordered, completely unusable. Seller demanded I send pictures before they would CONSIDER authorizing a return with a vague promise to send me what was originally ordered. I assume if I jump through all their hoops, more junk would arrive a few months later.
