The product is good- but find another seller. This transaction was one of my worst on Aliexpress. After a shipping problem caused by the seller (the ordered goods were not complete) we agreed that they will add the missing part to the next order. Just worthless promises. So - stupid me - I did an additional order from this seller and they still didn't add the missing article. We are talking about 4 USD. If this is worth a bad feedback - you are welcome - here it is. Don't trust negotiations with that seller. Seller has very poor after sales service. You will not get what you agreed on.
