I am really hoping someone here can help me. I bought a Brinsea Mini Advance used. They didn't have the box or directions, so I've looked up the PDF for instructions. Then stuck some eggs under it. It seems like it's holding it's temperature perfectly. However, I'm pretty sure the egg turner isn't working. I put x on each egg so I could monitor that and they don't seem to be moving at all. The / thing in the bottom corner does move around, and it's set to "automatic". I think I have it set to 45 minutes, and angle (?) of 15. I've hand turned them by moving the moveable plate in the bottom. I take the lid off to look at the gear thing, and it's not moving. I've gently tried to work it to see if it will move, and it doesn't, but i haven't been at all forceful because I don't want to break anything.
