I have been using these 22 oz. bottle for over 5 years. I don’t use the freezer stick. I don’t know if you are suppose to clean in the dishwasher but I do, even on the bottom rack. I order 6 at a time because they sell out fast. The 22 oz is a great size. I found the larger size to heavy when filled. The main reason I use them is I knock and spill drinks all the time. No spilling at work or watching tv.
I have used these as water bottles for years and really enjoy them! I was glad to find the website so I could order more, and in different colors. My favorite colors are the purple and Aqua. I was sad they were out of the Aqua, but hopefully in the future they may have it again.
