B,
I have just finished a trip on one of my bikes which has a Givi topbox. The construction is excellent and the box sits very well on the bike ( BMW ). I went through some rain but not enough to test the waterproofing characteristics. With the box alone the bike was quite stable in the wind as well. One word of warning, however. Don't put too much gear in so that you have to pressure the lid shut, or it will distort the plastic and put the side locks out of alignment.
