I paid for express shipping which should have taken 2-3 days as stated when checking out but my product didn’t show up until a week later. The gel that was also supposed to be included with the doppler was not in the package. I tried reaching out to customer service with the emails provided on the website as well as in the confirmation email of my order. They have not responded at all and almost all of my emails bounced back due to an invalid email address. Horrible experience!
