These were quite a bit lighter than the Zinc’s that I’ve used in the past. To test them out I used on of the heavier brand ( more expensive) and one of these. Same performance at half the price!

Second time buying this anode. I assumed I needed it and to my surprise when I pulled the boat after 18 months on the water the wear was minimal.
