Purchased the Navigat'r 6, the compass doesn't work. To get a replacement I would need to pay to ship back (of course I already paid for shipping to me) AND I would have to include an $8 check for them to send me another one. Good grief, with all the shipping charges I could buy something local. Thanks SunCompany for taking my money and selling me junk.
