Winterizing kit is AWESOME!
I’ve been using the wintering & opening kits for years. They make opening a breeze.
The winter kit is easy to use & makes quick work of closing. It keeps the water sparkling all winter long. I have a lot of oak trees and even when I don’t get the leaves scooped off my mesh cover quickly the water stays clear.
My region also has occasional very warm days all winter long and still, no issues.
I will use the winterizing and opening kits from in the swim as long as I own a pool.
