Question: 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.

Answer: negative

Question: This product makes you scan a QR code that goes to a Chinese(?) website. When you scan code it redirects you to an app which you have to download. Very sketchy. Don't buy, spend the money on a legit apple product.

Answer: negative

Question: I never write reviews but look at them for everything. This unit works perfect with SONOS and being able to run Apple TV, Fire Stick, or Cable to a 4K projector that does not have optical input. Took me awhile to find the right switch and this one does the trick. Full 5 channel surround and I confirmed my projector is running 4K.

Answer:
positive
