Same as Grillo on Wikipedia. I own a Globalsat DG-100 which I
am used to be very pleased with. It's now broken. Also, the only working user interface is a buggy application only usable in Windows 7. I used to map towns around Lund in southern Sweden with car and my irl friend User:Spull. Now I'm primarily focusing on mapping buildings and numbering them. I have also mapped rather extensively in south-eastern Scania.
