Bought this item as a new item as described but when item was received part of ceramic around power wire was broken it was taped together possibly to protect it or to hold it together do not know. Could have been broken during shipping which means it was not properly secured (wrapped) during shipping. Other issue is that is was to be a new item but it had a burnt smell to it and my mechanic stated item was used before burnt smell was from electrical load added to it. Possibly bench tested do not know. Mechanic installed in vehicle after some glueing part together. Burnt smell could be smelt inside vehicle while driving. But unit does work. Which is what I was hoping for. Now how long it will last has to be seen.
