I have something similar but doesn't have a hose attachment, just pump and then spray, it is awesome and sprays really well, wish it did have a hose because I am also misting crested geckos and find if the container is tilted and not full it looses its suction quickly!!! For my Cham though it is great as I don't have to tilt container at all
These are good for when you want to provide a long mist but don't want to constantly have to pump the mister with your finger. This you can just pump up the pressure and hold the trigger down, or lock the trigger on.
