The quality is top notch. You will not be disappointed. Probably the best bargain on a set of hard bags I've found.
Removal of the Viking logo is simply two tiny screws, that logo is the cheapest thing on the bag. A thin piece of plastic that looks like it can from the dollar store discount bin

I'll be ordering a set of easy brackets as I want to be able to easily remove them. The mounting hardware that came with the bags is "ok" I'm sure with a bit of ingenuity and a spacer or three you could make these work.
Just holding them up to the bike they look real sharp.
For the money I'm very pleased.
