The gun is advertised as having an easy depth adjustment. It does not have any that I can find. If you set the PSI to the lowest operating level it still fires the nail way way too deep. If you crank it way low it still fires too deep. If and when you ever get the psi low enough it will fire one correct nail then jam up. This gun is worthless to me. I could have used a hammer and nails and had way less head ache. I am hoping someone from Vevor can help me figure out the issue
