Does what it is supposed to do. The Marine version provides bolt on terminal options as well as traditional battery terminal connection.
Suggestions for the manufacturer: I wish it had a manual reset button as a backup to the automatic reset. I disconnected the ground wire to achieve the same effect though when it didn't reset one time during my install testing with various battery configurations. Might not be necessary in real life though. I think it would also be useful to be able to select from a few cutoff voltages instead of having one fixed cutoff voltage. I might want to set a higher voltage to leave more reserve power.
