I like that it gives me peace of mind knowing my product is protected from counterfeiters when sending out to customers around world! If there are any issues or questions about our products we can easily find answers in their support system so not much dislike here but if you have some queries regarding how they work please get them resolved as soon i did this was no problem at all!! We feel better now because its easy for us know what happens after an order has been placed by customer who may be overseas etc.
