You bye, seller send you the tracking number, you track and find any info, after a few days the seller deleted the product and you have to wait long to get your money back.
Not all buyers say from this and they make money from some buyers.
Or they will stop clone buyers.
You may want to check the correct sales nature of these sellers, selling lots and no feedback.
I think probably we have to wait until June 2014 with vu duo2
The seller has many products and no feedback I've checked.
Vu Duo2 clone is not confirmed for sale yet either.
You can buy one now at that price let me know.
I will also have duo2 clone.
But are satisfied with Solo2 V2
