Very satisfied with my mighty mni purchase. Got it when Rainier brought them out, it's been working great. It's getting hard these days to find quality built satellite products with all the junk coming in from foreign sources. Rest assured when you buy from Rainier your getting some of the best fully tested products out there.
As far as support goes Rainier is top shelf. They have a very knowledgeable staff that always answer any questions I have. The nice thing about Rainier is you can speak with a person on the phone that's in the U.S. not like with other companies. Their number is 509-486-4137.
If you haven't dealt with Rainier yet give them a try. You'll be pleasantly surprised.
