Safety matters to me, especially if I am using it around water systems. I look for clear safety instructions and proper handling guidance. I also keep it stored away from children and pets, even if it is labeled non-toxic, because I still want to be careful.
My Thoughts on Value
When I compare options, I do not just look at the lowest price. I think about how much protection I am getting for the cost. If a bottle gives me reliable freeze protection and is easy to use, I consider that a good value. For me, saving a little money is not worth risking damage to my RV or boat.
Storage and Shelf Life
I also think about where I will store the product after buying it. I keep it in a cool, dry place and make sure the cap is sealed tightly. If I have leftovers, I want to know they can be safely stored for next season without losing effectiveness.
