Those look pretty solid for hardcore transportation needs, but I always find that these storage solutions ignore your foam windscreens which get trashed quite easily. I like to use a simple heavy cardboard mailing tube that fits snugly around the mic with windscreen. They work quite nicely for everyday use, come in a variety of sizes and cost next to nothing to replace.
I do love a DIY solution--fly fishing rod storage tubes are great for boompoles!
