If the photo is of the actual regulator that is for sale I wouldn't get it. The outlet pressure range is much greater than is optimum for our uses. You would barely be able to tell the difference between 10 and 15 psi, and that is a big difference for an aquarium regulator. I always look for a regulator that lets me easily adjust the outlet pressure between 10 and 30 psi, with accuracy. You can't just replace the gauge either, because a lower pressure gauge would be ruined easily if you accidentally set the outlet pressure too high.
