I have one with the regular cap & I love it. I use it every day. A month ago I was in my kitchen getting supper when I filled my bottle to the very top with water like I always do. This time however I put it in the freezer thinking I would pull it out in 10 minutes. I looked for it for 2 days & finally found it frozen solid! I am so impressed with it because nothing broke. It distorted the main section a bit, but I have been using it for a month & it still works great without a single leak! Do you sell just the main clear body? I should replace it because it looks crooked. I have pictures if you care to see them. GREAT PRODUCT!!..Thank you!
