didn't come at all and they didn't want to refund me
on the package was no discripsion witch battery I had to put in the controler !!! I have contact the seller and after 4 days I had contact them again (they asked me in the first contact to do this when I had no responce in 3 days ). that's oke. that's the only negative point. the conversation was excellent and friendly and I am verry happy with the product. I have got the right information the second time.
