PLEASE AVOID !!!!!!READ ALL THE PURE REVIEWS ALL OVER THE WEB FIRST Once you pay,you have lost your money for NOTHING!! Not better than the 9.99 Amazon ones.And I got the expensive ones They will ask you to try for the impressions so many times ,until you'll give up and NEVER get your money back. They were keep asking me for more and more impression samples.I was feeling stupid..Then I said that I am sending the last one and ask for a refund.They accepted It! But this time I did not even follow their detailed,"must do" instructions!!! I boiled the impressions for 3 min and then waited for 1min.And they have accepted It!!!!!!! Why? If you read the small letters,then you will understand why they keep asking you for more and more samples!! A SCAM !!! From the time you will pay them,be sure that 3 things will happen 1)You have lost your money 2)You will be surprised with their product when you will receive it and find out that it is the same like the ones in Amazon.!!3)You will feel SCAMMED and like an idiot!! The reviews rated above 1*,are from their people...Read the REAL ONES.. Worse buy EVER!!! I suggest all disappointed customers to join together and take legal actions against this company.. THEY GET 5* ONLY IN THEIR SITE !!! NOWHERE ELSE !!!🤣
