Biggest disappointment ever

Brilliant service from ordering until receipt. Battled to figure out how to fit the core into the necklace, and eventually, after forcing it in, I could use it. What a disappointment. I am not sure what I expected, but I would not have bothered if I knew that you would have a 0,1% flavour with normal air coming through the necklace when using. Do yourself a favour and find out if someone you know knows someone who uses this product before wasting your money.
