In short I recommend.
EDIT 12/01/2015:
After my negative opinion, the Seller contact me to offer me a refund of the product, but only if I withdraw my negative comments !!!! Purchase avoid doubling!
As you can read this advice, you can imagine that I do not tolerate this kind of manipulation! The product is bad, I signal, you repay me, fine, but NO I do not withdraw my opinion! On the contrary !!
Beware to seller! Especially if there are only positive notes! And do not agree to remove your negative opinions about a product if the seller offers a refund! Otherwise in 1 year there will be more than product 5 *
