I have purchased 2 for 1 dash cam when I saw their add through Facebook and ordered it in Sept 1, 2017.  After 2 weeks of no product being delivered I contacted them thru email.  They said they did not anticipate the high volume of orders so it may take more time to get it delivered.  After a month of waiting I have decided to have it cancelled they emailed and said it will tke 5-7 business days to get my money back to my credit account and I will be receiving email in regards of my cancellation.  NO email received and my MONEY is NOT BACK and it has been over a month since the cancellation.  I tried emailing them to see the update but they did not reply to my last email anymore.  I payed $139.80
