    Very fast shipping and well packed items these guys are professionals. The chat is the sh**, there is always someone to answer and they are very comprehensive, all questions answered quickly and accurately, very helpful if you’re unsure about anything at all. The product hasn’t been thoroughly analysed yet, but all of the first tests were promising. Go for it !!!
