Q: It doesn’t work. Don’t buy from this seller. I can’t return it. It was a gift to my husbamd who is always out of town. By the time he got to it, it was passed the return date and I cannot contact Amazon about this item since they’ve changed the layout. It was an expensive mistake. Don’t buy.
A: 
negative
