I like the Hi-Aerial hoods. They fold flat for easy backpack storage, plus they are pretty simple and quick to install on the RC. They are a two piece unit, but I rarely use the second piece that makes it twice as high. These are way more rigid than the Hoodman units, easier to install. The base unit only is about $60, that's all I typically use. Occasionally you'll see them go on sale for around $50. Mine is for the iPad Mini, I'm not sure if it works with the K1, the connectors may be located different. You'll need to call MIke Harris and ask, (403)360-8338
