When using the Flim Flam shop be very careful as they refuse to replace any products that do not perform to expectations. I bought some ipad spiders through them and after one month of very light use in a car they both have a broken arm each. Not only that but the order took 3 months to complete and now that the spiders don't work they are not interested. Better to go direct to the manufacturers and cut out Flim Flam middle men!!
