Where is the rest of my order!?
By Bullyboy from Oswego,NY

Verified Purchase

Product is very good, even though it is made in china. You never ship a complete order, always have to wait for something.

Bottom Line Yes, I would recommend to a friend

Rudder Tab Magnesium Anodes
By THOMAS HR from HARTWELL, GA

Verified Purchase

We use this as we are not in Salt or brackish water. Only way to fly as Zinc does not work in fresh water. We change out every year. Unit on copper condenser we change out every other year. We have grounded every thing on the boat. Power is supplied by PM alternator.

Bottom Line Yes, I would recommend to a friend
