If you are not getting any replies to you question here it is because no one has the answer.
You've asked has anyone heard of it?
You can't expect 100 members to all say...NO, WE HAVEN'T HEARD OF IT!
I think you can take it from the lasck of response that no one who has read your post has in fact heard of it as yet.
When someone has an answer to your question then they will share it with you, and all the members.
You may want to also consider contacting jimmy from salehoo staff if an urgent response to your question is required.
