The product does work well with the biggest benefit to safer sailing. It also makes reefing a no-effort exercise. It is easy to pull out the reef and raise the main back up if desired. I tend to reef sooner knowing this. The benefits are just too great. And the fun of how the sail drops instantly, you will enjoy this product and increase your safety profile.
For a due diligence effort you might want to check out the Antal line, very high quality product and it has been around a long time. See here --> Home
. I did a bunch of research on the product, very solid also.
