Impressed with quality. Be aware no mounting hardware
I'll leave this as per my title. Price was right, quality seems right. I'll mount it after bottom painted.

Works well, lasts longer than Martyr and does not crumble when well worn
I buy these Sea Shield MIL+Spec zincs from my wholesale supplier, but these offered by Amazon are the same. They use a superior zinc alloy to Martyr, they last longer in the water, and do not quickly crumble when they have been reduced to less than 40% as much of the competition does. The steel slides hold up well, and having used these for years on my own ocean going boat, there is no corrosion or pitting on any other metal that is protected by these zinc plates.

It will take time to judge the products ability to protect my boat engine and running gear.
Delivered on time. However I can't comment on the results because it will take time too judge how well it will protect my boat engine, etc.

Heavy duty
Easy to install. Boat has been in the water a month and I haven't noticed much deterioration.
